Caught in the squat

Dan Cullum · Mar 26, 2024 ·

If you’ve ever done squats as part of a strength training programme, you’ll know the importance of keeping within your limits.

Go too heavy, too quickly, and at the bottom of the repetition you’ll get caught. You won’t be able to return to a standing position, and you’ll need to let the bar fall behind you to the floor or the safety racks.

There are many benefits to squatting, but operating that close to our max weight adds a significant number of physical risks. It’s much better to go lighter and to do more repetitions.

This concept applies far beyond squatting to almost any difficult activity or endeavour.

Pros play at the edge

Dan Cullum · Mar 25, 2024 ·

When playing darts, beginners aim for the bullseye.

But there’s a thin strip at the edge of the board where triple are available. A player can earn more points than a bullseye, but there is also more risk. There is also a chance of ending up with no points.

It should come as no surprise though that the pros play at the edge. They’re conditioned to the risk, and relentlessly pursue the reward.

Where do you choose to aim for the bullseye? And where do you play to the edge?

Bits and bytes

Dan Cullum · Mar 24, 2024 ·

No matter how long we work in an industry, we can still learn new things—even things that are seemingly basic!

In a post earlier this week I confused bits for bytes. Despite working in tech for almost a decade, I’ve never had to work at the scale of a bit before, so I’m giving myself a break here. But if you want to dig into it, or need a refresher, try here.

One part about writing in public is not going back and changing the past via the edit button. The reason I don’t use the edit button is because it’s a lesson in how to handle real life challenges. For most mistakes, we can’t just hit the edit button and perform revisionist history. So sure, little grammatical errors can be fixed retrospectively, but at the post level, the bigger picture is about about embracing mistakes and learning for next time.

Cultivating this mindset on the small things prepares our minds for bigger challenges and mistakes.

H/T to Sri for spotting my error and letting me know about it!

Goals and the future you

Dan Cullum · Mar 23, 2024 ·

Most people write goals for who they are now, for where their organisations are today, and for how people around them expect to perform and grow.

But what if we wrote our goals assuming a certain level of personal and organisational growth. I think this little bit of extra optimism and vision will result in more ambitious goals, and a better visualisation of what could be.

And I think that little bit extra counts for something.

1gigabyte

Dan Cullum · Mar 22, 2024 ·

When I was a kid—about 12 years old—broadband had data limits, and the default offer was 1 gigabyte per month.

When my family upgraded from dial-up to broadband, this felt like a huge amount of data—and more importantly, speed!

Today I just organised the broadband for our new flat. There are no data limits anymore, and the package’s network download speed is 1 gigabyte per second.

In the space of 20 years, we’ve gone from my family’s entire bandwidth allowance for a month, now being used in a single second.

I think that’s pretty cool.

Are you baking or cooking?

Dan Cullum · Mar 21, 2024 ·

For whatever project we’re currently working, we need to figure out if we’re baking or cooking.

Baking requires precision. You need to follow the steps exactly. That means the right quantities, ingredients, temperatures, and timings.

Cooking, on the other hand, is more improv. You can substitute, adapt, add, experiment, and taste along the way.

Both lead to great tasting outcomes, but get there in different ways.

Problems worth turning up for

Dan Cullum · Mar 20, 2024 ·

Problems are everywhere.

In our jobs. In our relationships with friends and family. In our hobbies. In life admin.

We can’t solve them all though. There aren’t enough hours in a day.

So we need to choose the problems worth turning up for.

The rest can wait.

Seeing sun at 5pm

Dan Cullum · Mar 19, 2024 ·

Seeing the sun in London at 5pm in March means the end of winter is coming, and we’ll soon be welcoming spring and summer.

I love when this day arrives each year. Although it’s not marked by a date or an occasion, it’s a very peasant surprise, and a realisation that the worst of the winter is behind us.

It hints at warmer days to come, and long sunny evenings with friends.

I inevitably end up writing a post about this day each year. But after a long winter, I feel it’s well deserved.

When everyone knows the rules

Dan Cullum · Mar 18, 2024 ·

I was sitting at a traffic light today, and cars were backed up for at least 50 metres on each side of the road waiting for the lights to turn green.

Up ahead and in the distance, I heard the sound of an ambulance approaching. I saw its lights reflecting off cars and buildings before it arrived at the backed-up line of cars.

The traffic lights in front of me turned green, but no car moved. All of us remained in place, allowing the ambulance to use both sides of the road to weave through and get past the gridlock with ease.

Systems are typically designed with order being the base case or day-to-day expectation. But when there is an emergency and the system is under stress, it only works when everyone knows the rules. And crucially, when everyone know how to implement the rules in unison.

World of the Wolves

Dan Cullum · Mar 17, 2024 ·

I was on the train to Birmingham earlier today, and as the train passed through a bunch of towns just outside London, the carriage filled up with football fans. Specifically fans of the Wolverhampton Wolves, who were on their way to the FA Cup Quarter Final happening later that day.

It was like being dropped into another world. They talked enthusiastically about player transfers, manager performance, and budget constraints. They debated the pros and cons of their team’s current strategy; offering ideas for how it could be better. They compared themselves to other teams, and tried to figure out why some teams were succeeding and others failing. They chatted with friends and strangers alike with openness and a hopeful energy for the game ahead.

Once we pulled into Birmingham, the fans peeled off in one direction, and I in another. But for a brief moment on that train, I got a fascinating glimpse into the world of a Wolves fan, and I get why people return week after week, year after year, to support their club.

Optimising for curiosity

Dan Cullum · Mar 16, 2024 ·

When we follow our curiosity, we often have endless energy to learn, explore, and grow.

But when we have little interest in what we’re doing, it takes immense will power to just show up.

There is a world of work, personal projects, and hobbies out there. What would happen if we optimised more deliberately around our curiosity? What would be different?

Admire the view

Dan Cullum · Mar 15, 2024 ·

Maru and I are moving flats at the end of this month. Our landlord is selling, and we’re reluctantly leaving the place we’ve called home for almost four years.

We got lucky with this one. Given how flat London is, there aren’t many spots with views of the skyline. We have an unobstructed view of the city and get to see stunning sunsets when London decides to not be overcast.

Maru has always been good at pausing and admiring the view. I’m trying to join her in this good habit. The benefit we get from that little pause far outweighs the minimal cost incurred.

Customisation costs

Dan Cullum · Mar 14, 2024 ·

The base price is rarely a problem. It’s the customisation that costs us.

It doesn’t matter if it’s a memory upgrade for your Mac, the add-ons for your home renovation, a client that wants a bespoke feature added to the software, or a tailor-made suit. It all adds up.

But sometimes, it’s the customisation that makes the thing magical. And sometimes, that magic is worth the cost.

Imperceptible growth

Dan Cullum · Mar 13, 2024 ·

Measuring growth on a daily basis is futile. Progress is imperceptible.

Give it a few months, however, and we start to see the fruits of our patient, consistent effort.

The photo below is of one of my terrariums taken in October 2023; with Spock sitting comfortably in the middle.

This is the same terrarium in March 2024, with Spock now enshrouded in moss and plants.

Sequels and survivors

Dan Cullum · Mar 12, 2024 ·

Why are sequels usually worse than their originals?

Survivorship bias.

Out of all the films produced in a given year, only the best get a shot at a sequel. So when comparing the success of a sequel to an original, the “bar” is a comparison against the best, not the average.

There is a graveyard of less successful films that never got a chance at a sequel.
