Self-proclaimed “popstar for dorks”

Dan Cullum · Sep 3, 2019 ·

It’s a real privilege to share the latest single, All The Hours, from my friend, Geoff Ong.

Geoff has been tirelessly self-recording and self-releasing melodic pop tunes for the past 5 years, and his level of commitment to his craft has always inspired me.

I also love how Geoff leans into his awkwardness in his music and promotional videos, and how he’s a self-proclaimed “popstar for dorks”. It’s been such a pleasure to follow this genuine, talented artisan on his musical journey, and I hope you give his music a try too!

You can check out Geoff’s new single, as well as his other songs, in the Spotify player below.

The cost of not doing it

Dan Cullum · Sep 2, 2019 ·

We typically weigh up decisions based on their cost to us.

How much will the vacation cost? And those insurance premiums? How much will I save with Supplier A versus Supplier B?

However, a recent conversation with a friend opened my eyes to a new way of thinking about cost: the cost of not doing it.

I was complaining to them about the price of gym memberships in Central London, to which they replied, “Well, what’s the cost of not taking care of your body?”

I’d never thought about cost in this way. She pushed me to think about the long term consequences of not exercising, rather than the short term impact on my bank account.

This idea is powerful because it extends effortlessly to other areas of our lives:

  • What’s the cost of not eating whole, nutritious foods?
  • What’s the cost of not taking time-off from work to rest and recharge?
  • What’s the cost of not investing into one’s education outside the workplace?
  • What’s the cost of not spending time each week with family and friends?

What’s the cost of not doing it?

“Hey, Siri. Stop listening.”

Dan Cullum · Sep 1, 2019 ·

I was surprised to learn this week that Apple will stop the default recording and storing of Siri conversations.

Sorry, what? Apple’s doing that?

Yep, about 300 of Apple’s European contractors had access to recorded Siri conversations as part of a project to improve Siri’s artificial intelligence.

This process is called “grading”, where humans listen to recorded Siri conversations to identify, report, and correct errors, such as Siri responding when the user didn’t intend to wake her.

As someone who is relatively relaxed about their personal data privacy (we’ve got an Alexa and I’ve never performed a personal data privacy audit, but I do have a paid password manager and two-factor authentication set up where possible), this spooked me.

Perhaps naively, I thought Siri’s artificial intelligence was trained on a small subset of opt-in users, and didn’t realise recording my conversations with Siri were recorded by default.

Apple has now suspended default recording and storing of Siri conversations, and I think it’s response to the criticism has been pretty clear, but this learning has encouraged me to audit my personal data privacy settings across the rest of my digital life.

Do you have any tips or tricks for protecting your data online?

Between the lines

Dan Cullum · Aug 31, 2019 ·

A great nation is like a great man: when he makes a mistake, he realises it. Having realised it, he admits it. Having admitted it, he corrects it. He considers those who point out his faults as his most benevolent teachers — Lao Tzu, 600 B.C.

This quote is more than just a vision for a great nation or person. Between the lines, it provides a hidden prescription for how to get there.

To realise our mistakes, we need self-awareness.

To admit our mistakes, we need humility.

To correct our mistakes, we need a bias for action.

To cherish those who point out our faults, we must listen with care and discernment to those who give us their feedback.

I’m going to be pondering this quote, and it’s hidden prescription, for a long time.


On a semi-related note, I’ve recently been think about cataloging great quotes and trying to commit them to memory. I’d love to hear from you if you know of any helpful methods for storing, organising, or memorising them.

Harley crazy

Dan Cullum · Aug 30, 2019 ·

There were 4 couples in their late fifties sitting two rows in front of me on the flight from Los Angeles to Auckland. They were clearly part of the same tribe.

Harley Davidson. Head to toe.

T-shirts. Bags. Sweaters. Cowboy hats. Tattoos.

It looked like they were returning home from a lengthy motorcycle tour, and they wanted the world to know.

It was an in-your-face reminder about the power of brand.

These couples identified so strongly with Harley Davidson that they were willing to dress exclusively in its merchandise, and tattoo their bodies with its logo.

It got me thinking about how I’ve never seen someone with a Toyota tattoo, or voluntarily wearing one of their t-shirts. Sure, Toyota and its cars have reliably served millions of families around the world for many years, but its brand doesn’t elicit anywhere near the same adoration or dedication as Harley Davidson’s.

The Harley Davidson story doesn’t resonate with me, but it’s a fascinating sub-culture to observe to learn about the power and influence of a brand.

Posting at 900 kph

Dan Cullum · Aug 29, 2019 ·

As I post this, I’m in a tiny metal tube at 35,000 feet, somewhere over the Atlantic Ocean, and hurtling at 900 kph from London to Auckland.

Who thought wifi in the sky was a good idea?

We’re already always connected, and plane journeys were one of the final few refuges from unrestrained communication in the connected age.

Despite my gripes, I am grateful for one thing about wifi in the sky. With a 40 hour door-to-door journey, it was going to be tough to release my daily post on time.

Thanks to wifi in the sky for helping preserve the streak!

Now, back to disconnection.

Letting roots take hold

Dan Cullum · Aug 28, 2019 ·

4 months ago, Maru and I went full-blown millennial and signed up for a terrarium building workshop.

A terrarium is a sealed glass container to keep small plants. They are a self-contained ecosystem, and a beautiful microcosm of our earth’s environment. By recycling their own air and water, they can survive with minimal care.

Maru and I each made our own, but 4 months on, the health of our terrariums are vastly different.

Dan’s Barren Wasteland
Maru’s Garden of Eden

We followed the same instructions. We put in charcoal to absorb impurities, added pebbles for drainage, filled it with quality soil, and watered them with 10 light puffs from a spray bottle.

So why is Maru’s healthy, but mine looks like the setting for the next zombie apocalypse movie?

After some searching, we found our answer.

When transferring young plants from plastic pots into a terrarium, you need to place the roots at least 1 inch deep into the soil.

Maru followed this instruction (of course), and the roots of her plants grew healthily throughout the jar. I, on the other hand, didn’t press the roots in deep enough.

For the first two weeks, all was well in Dan Terrarium Land, but soon after, my plant’s leaves began to turn brown and wither. They weren’t able to absorb nutrients and water from the soil, and the decaying leaves triggered the moss and mould that have since taken over the jar.

When making a terrarium, you can do everything else right, but if the roots don’t take hold, all the other work is meaningless.

Reflecting on this experience got me thinking about a parallel: how we absorb what we read and learn.

Embarrassingly, despite reading a fair amount, I find myself forgetting a lot of it. It’s a constant wish of mine to retain more and forget less.

When we read at pace but fail to internalise or practice the learnings, we’re like a plant with shallow roots. Unable to absorb the nutrients required to grow.

As the late Stephen Covey once said, “To learn and not to do is really not to learn.”

My unhealthy terrarium has encouraged me to slow down. My learning journey isn’t a race. Rather, it should be deliberate and considered, with time consistently set aside to absorb and practice.

The next best move

Dan Cullum · Aug 27, 2019 ·

There is one guaranteed way to get better at chess.

Once you’ve decided on your move, but before you’ve made it, you should: 1) identify the next best move available to you, and 2) justify why the original move is better.

This process can help us uncover a better move that we may have missed, and ensures we don’t default to the first, obvious, or easy solution.

Unsurprisingly, this method can also be used to improve general decision making.

Although we make thousands of decisions every day, most of them don’t require complex analysis or thinking. However, for important decisions, using this process gives us pause, allows us to explore alternatives, and ultimately increases our confidence in the decision.

Compounding small errors, and the margin of safety

Dan Cullum · Aug 26, 2019 ·

Most mistakes are inconsequential. They are small errors that occur in isolation.

However, there are some situations where small, interdependent mistakes can compound to produce grave consequences.

This weekend’s Sardinian diving experience had me reflecting on this idea.

Diving is a safe activity when performed correctly. However, like any sport, there are things that can go wrong. For example:


  • You could become separated from your dive buddy
  • You could get lost and lose track of the dive boat
  • You could forget to regularly check your oxygen supply

Most of these mistakes, if they occur in isolation, have an easy fix:


  • If separated from your buddy, do a 360 degree turn, look for their bubbles, use an audio signalling device, and flash your dive light.
  • If you lose track of the dive boat, ascend slowly, and after performing the required 3 minute safety stop at a depth of 5 meters, you can surface using an inflatable diving buoy to let the dive boat know your location
  • If you forget to regularly check your oxygen supply, your buddy will usually remember and you’ll be able to make a safe ascent with oxygen to spare

However, it is when these mistakes occur simultaneously that the risk compounds. The emergence of a second or third problem may prevent us from being able to solve the first, let alone all of them at the same time.

To protect against these situations, we build in a margin of safety. These are checks and processes to minimise risk. In diving, we’re trained to an international standard, we look at the weather report, we triple check our gear and our buddy’s, we discuss the dive route beforehand, and we make sure we’re clear on what we’re going to do if something goes wrong.

Having these processes, this margin of safety, gives us confidence.

The usefulness of the margin of safety concept extends well beyond diving. In any situation where there is significant risk, it encourages us to think ahead and protect ourselves from the worst.

Travel insurance is a good idea. Diversifying your savings into varied investment types is too. Even something as simple as routine stretching before exercise can help prevent painful, long-term negative consequences.

In which of your activities could you apply the margin of safety concept?

Wreck diving in Sardinia

Dan Cullum · Aug 25, 2019 ·

SCUBA Diving is otherworldly.

The human race has only had SCUBA access to the underwater world for 80 years. To put that into perspective, that’s the equivalent of 0.001% of Homo Sapiens existence.

Prior to this, seeing and exploring the depths of the ocean were impossible. We were constrained by our tiny lungs, an inability to see underwater, and a complete lack of understanding of how to overcome the challenges of changing water pressure.

Understanding that history made me so grateful for the experience we had diving with friends yesterday in Sardinia, Italy. We explored a reef and a Greek cargo ship, called Angelika, that was sunk back in 1982.

There are more reflections to come on this experience, but before that, here is a 1-minute film we made summarising our dive.

The rain always stopped

Dan Cullum · Aug 24, 2019 ·

Whenever it’s rained, it’s eventually stopped.

No one looks at the cloud-covered sky and says, “We’ll never see blue again.”

No one feels the biting winter gust and utters, “This will never end.”

Sometimes, though, it can feel never ending.

This reminds me of the famous Robert Frost’s response when asked at his eightieth birthday party, “What is the most important thing you have learnt about life?”

“In three words, I can sum up everything I’ve learned about life. It goes on,” he replied.

Come what may, life will go on.

H/T to my father-in-law, Salvador, for sharing this idea with me.

There’s always something in the box

Dan Cullum · Aug 23, 2019 ·

When I started daily blogging, I was concerned that I’d run out of things to say. And to be honest, I’m only 1 month into it, so it’s still a fear. But it’s been allayed, somewhat, by a maxim from the world of Improv Theatre.

“There is always something in the box.”

There is an exercise where students in an improv class take turns at opening an imaginary box. The natural instinct is to prepare; to think about what’s in the box before it gets to you. Students are discouraged from doing this. Instead, they are encouraged to wait until the box is passed to them, to open it, and to genuinely respond to whatever appears.

They are asked to trust the process. To trust there is always something in the box. To trust there will be something to react to, to share, to be generous with.

Showing up every day and trying to write something thoughtful and generous can feel uncomfortable. Particularly when you’re having a hard day, or feel lacking in inspiration.

However, even in the last month, I’ve seen evidence that there is always something in the box. There is always a new way to look at the world.

What’s in the box may not be earth-shattering everyday, but that’s okay. That’s not the point. The point is to respond as best as possible to what ever is there, in the hope that it may resonate with someone else.

Start-up learning allowance

Dan Cullum · Aug 22, 2019 ·

One of my favourite things about working at Bulb is the learning and development allowance. Each employee receives £1,000 to invest in themselves as well as 5 days study leave per year.

Employees can use the allowance on conferences, courses, and accreditations. I use the majority of mine on books, which has given me the ability to read beyond my normal business-book niche and explore the topics of psychology, philosophy, writing, and mathematics.

Even more than the allowance, I love what this policy communicates about the autonomy and trust given to employees to chart their own learning journey.

It encourages self-awareness and proactivity, and leads to employees gaining skills that make them better at their job.

Some would say this is an expensive programme, but what’s the cost of not doing it?

Data vs. Taste

Dan Cullum · Aug 21, 2019 ·

We typically use a combination of data and taste to make decisions.

With data, the numbers suggest one option over another.

With taste, experience and our gut bring us to a conclusion.

In the same way we don’t like the temperature being too hot or cold, we don’t want to lean too far toward data or taste when making decisions, as this can lead to expensive mistakes.

As a general rule, when data is available and it is trustworthy, we should use it.

But even if we have good quality data, we should also use taste as a common sense check when releasing anything new into the world.

Proximity

Dan Cullum · Aug 20, 2019 ·

If you’re the only one selling water in a desert, and there are thirsty people around, you’re likely to make money.

You could make them wait in line for 2 hours, charge a criminal price, and sell it with a scowl; they’d still buy.

Sometimes, proximity wins customers.

That’s the Convenience Store model. Over-priced products with poor service, but available immediately.

However, there is a way to succeed without relying on proximity.

It requires consistency over many interactions. It requires making something worthy of sharing, or waiting in line for. It requires taking care with each detail.

At that point, we earn the trust needed to serve those beyond our immediate proximity.
