Growing opportunity costs

Dan Cullum · Sep 15, 2024 ·

When I learned about opportunity cost in economics, it was just an abstract concept. Sure, I understood that every choice has a next best alternative, but I didn’t see the concept playing out in my day-to-day life.

Almost 20 years on, I’m seeing a pattern that our opportunity costs grow as we get older. We have more commitments and harder trade-offs to deal with across our time, money, and energy. When we say “yes” to anything, we’re also saying “no” to a larger and more valuable set of alternatives.

We’re not going to escape this transition to higher opportunity costs, so it’s our responsibility to put the necessary thought into our trade-off decisions. If we’re not consciously choosing, we’re letting someone else choose for us.

Close enough to see the spittle

Dan Cullum · Sep 14, 2024 ·

I’ve made the mistake of buying nosebleed theatre tickets one too many time, and each time I’ve regretted it. I can’t see the facial expressions of the actors, and I feel disconnected from what the actors are trying to look out.

So here’s a rule to ensure you get great seats at the theatre: sit close enough to see the spittle.

Actors need to project their voice to fill the space, and inevitably they’re going to spit a bit. If you sit close enough to see the spittle, you’re also going to be able to see every important facial expression, gesture, and subtle onstage action and reaction.

It’ll all adds up to an experience that is worth far more than the premium paid for the better seats.

Living in a good memory

Dan Cullum · Sep 13, 2024 ·

I recently heard about the idea of “living in a good memory”.

It’s when you’re simultaneously aware that (1) a good thing is happening, and (2) it’s going to become a memory. In that moment, you’re living in a good memory.

One example that comes to mind is our “family moon” after Maru and I got married. I remember consciously soaking up each moment; conscious they would become special memories.

Keep an eye out for “living a good memory” moments, because we can’t make the most of them if we don’t know we’re in one.

Mixed Idioms

Dan Cullum · Sep 12, 2024 ·

Mixed idioms are fun and little bit goofy. It’s when two well known phrases with similar meanings are mixed up—by accident or deliberately.

A few examples:

“Until the cows freeze over.”
(Until the cows come home; until hell freezes over)

“A walk in the cake.”
(A walk in the park; a piece of cake)

“Let’s put the elephant on the table.”
(The elephant in the room; lay your cards on the table)

Exercise logbooks

Dan Cullum · Sep 11, 2024 ·

For the last 2-3 months, I’ve logged every strength and cardio workout in a logbook; except for tennis, which I don’t really count as cardio.

It serves two purposes:

  1. It gives me a sense of accomplishment as I see the days and effort stack up
  2. It gives me confidence that I know where the baseline is, and how I’m progressing against the target

There is nothing fancy about it. A couple of books and a ballpoint pen. But that’s also the magic of it.

Pandemic Legacy Season 0

Dan Cullum · Sep 10, 2024 ·

Back in 2019, my sister, brother-in-law, and I played the boardgame Pandemic Legacy. I loved it and wrote about it here.

Legacy style boardgames are like a TV series, whereas typical boardgames are more like films. In Legacy games, there is a storyline that you play over many sittings, and the challenges and plot twists are revealed throughout. Legacy games tend to have a level of depth to the narrative and gameplay mechanics that make it serious fun.

Maru and I have recently started a new legacy game with some close friends: Pandemic Legacy Season 0. It’s pitched as the backstory to the original Pandemic Legacy and has us operating as spies during the Cold War on a mission to prevent a looming bio-threat. We’re all working together and solving problems as a team, which make the wins and the losses all the more exciting.

If you and a small group of friends are already into boardgames, I’d highly recommend trying out a Legacy game. It requires more commitment than a normal boardgames, but its well worth the effort.

4-7-8 breathing method

Dan Cullum · Sep 9, 2024 ·

The 4-7-8 breathing method is described as a “natural tranquilliser for the nervous system,” by its creator Andrew Weil.

It involves breathing in for 4 seconds, holding your breath for 7 seconds, and breathing out over the course of 8 seconds. And then repeating this 8 times.

It’s easy to find research supporting the benefits of mindful breathing: from anxiety reduction, improved sleep, and lowering blood pressure.

And I’ve found following the 4-7-8 breathing method works really well if I want to relax at the end of a long day, or if I need a moment of quiet during the day.

Give it a go!

From where, and by who?

Dan Cullum · Sep 8, 2024 ·

I bought some shallots the other day from Tesco and was surprised to see a label at the bottom of the bag: “Grown in Norfolk UK by Chris Kitchen”.

It’s a small detail, but there’s something about public accountability and knowing the source of our food. Whether it makes us feel closer to our food, or more mindful of its journey, or that there is always a name and face behind the packaging.

It’s a welcome addition.

A lot can change in 20 years

Dan Cullum · Sep 7, 2024 ·

When I was 11 years old I started taking guitar lessons. The way we picked my first teacher was simple: we got a single recommendation from the local music store, did a trial lesson, and that was that—he became my teacher for the next year. There was no comparison between teachers, no assessment of his skill level, and no way of knowing (without a lot of work) if there were better suited teachers out there.

The above was normal 20 years ago, but it’s a huge contrast with my recent search for a guitar teacher. I’ve become interested in a very particular 5-string tuning developed by Jacob Collier. Via YouTube I found a musician in Colorado that has put a lot of time and effort into understanding this tuning. So when I found out he gives lessons over Zoom, it was an easy decision for me. Within 24 hours of emailing him, I had paid for, and booked, our first lesson.

The internet is amazing.

Blocking vs. Obstruction

Dan Cullum · Sep 6, 2024 ·

Rugby and American football are similar. A team of people try move a ball down a field, there’s a lot of tackling, they score tries or touchdowns, and they kick goals.

There are also many differences, such as backward-only passing in rugby versus forward-passing in American football, Another difference is the topic of today’s post: Blocking vs. Obstruction.

In American football when the ball carrier is running up the field, their team mates can run alongside them and “block” opponents from attempting a tackle. The more opponents blocked, the better.

In rugby when the ball carrier is running up the field, their team mates cannot block opponents from attempting a tackle. If they do, this is considered an “obstruction”. In contrast to American football, the rugby player needs to face the opposition alone. If a defending player obstructs repeatedly, they get a yellow card and are sent to the “sin bin” for 10 minutes.

I love how in one sport an action is celebrated, whereas in the other sport the exact same action is considered foul play.

Extending this idea beyond sport, it always pays to know what game we’re playing.

Unexpected calendar benefits

Dan Cullum · Sep 5, 2024 ·

A number of you messaged me after I wrote about my big A0 calendar, and there was a quite a lot of interest in doing the same.

The main reason why I got the calendar was to visualise upcoming events, and it’s been really useful for that purpose.

However, an unexpected benefit is being able to look back at all the things that have happened this year: friends and family visiting, trips taken, and shows we’ve gone to. Those little markings on my calendar give me a snapshot of my year so far, and serve as a reminder to be grateful.

Take the thinking out of it

Dan Cullum · Sep 4, 2024 ·

It’s widely known, and proven, that brushing our teeth for a minimum of two minutes is required for good oral health and hygiene.

And although electric toothbrushes are widely regarded by dentists as being superior to manual toothbrushes, I think they stand atop the podium because of one simple thing: the two-minute timer. It removes the need for measurement and thinking. It turns an action critical for our health into something automatic.

Although the invention can’t be attributed to a specific person, I’m grateful that someone, or some group of people, back in the 90s pushed for this to become a standard across all electric toothbrushes.

The benefit to cost ratio is difficult to calculate, but I bet it’s insane.

Body battery

Dan Cullum · Sep 3, 2024 ·

You know how your phone gets sluggish and slow when its battery gets down to 5% charge? It takes a moment for apps to respond, and there is a noticeable lag between input and response.

Our bodies are the same. Hard tasks, difficult conversations, and deep thinking should be saved for when the body battery is fully charged.

Oasis miss

Dan Cullum · Sep 2, 2024 ·

If you read my post from a few days ago, you’ll know Maru and I were hoping to get Oasis tickets. Unfortunately, we missed out.

Even after waiting for 3-4 hours to get into Ticketmaster, there were 400,000 people ahead of us in the queue for our chosen concert date. There was no chance we were getting a ticket.

There’s been a lot of complaining online about how poor the ticketing experience was. Millions of hours were wasted by hundreds of thousands of fans who missed out.

It made me think that “live” ticket sales are antiquated, not to mention an impossible task for a ticketing company to manage at the point of peak demand.

Why not just have a ticket ballot that’s verified by mobile phone number? People can have many email addresses but are less likely to have many phones. And it would save millions of hours of wasted time.

What’s really important

Dan Cullum · Sep 1, 2024 ·

For the past six years, Maru and I have been playing poker with the same group of friends.

In all that time, our buy-in hasn’t changed: a token £5. And our collective poker skills have not improved; at all.

But now we spend much longer having dinner, and much less time playing poker. I think that, and the lack of poker improvement, says a lot about what’s really important.
