This mindset counters the all-or-nothing trap: if you don't have 100% of the information you do 0%, when you should just do 80% and optimize later. The mechanism is that consistency, not precision, drives results, so the highest-leverage move is to establish the basic habit before fine-tuning it. Get to the sauna once a week before debating 13 versus 15 minutes; eat mostly well before agonising over macros. Because 99% of people don't even have access to the 'optimal' version, the basics capture almost all the benefit. Small, sustainable steps that last beat dramatic overhauls that collapse. Attaching a new habit to an existing routine (drinking water while the tea brews) makes it stick.

Core principles
- 01Adherence beats optimization
- 02Small sustainable steps outperform total overhauls
- 03All-or-nothing thinking leads to doing nothing
- 04Fine-tuning only matters once the basics are consistent
How to run it
- 1
Name the all-or-nothing trap
Notice when you're refusing to act because you lack complete information or can't do the perfect version.
Pro tip The tell is 'I'll start once I know exactly how to do it right.'
- 2
Do the basic version first
Get to the habit at a minimal level, once a week, before optimising frequency or dose.
Pro tip Reaching the sauna weekly matters far more than the exact minutes.
- 3
Aim for roughly 80%
Accept that capturing most of the benefit through easy consistency beats chasing the last 20% and doing nothing.
Pro tip Most of the population can't access the 'optimal' setup and are still fine.
- 4
Optimize only once consistent
Fine-tune duration, timing and detail after the basic habit is reliably in place.
Pro tip Attach the new habit to an existing one so it sticks.
Watch out Optimizing before the habit is consistent wastes effort on something that won't last.
In the wild
Trying to recall whether the ideal sauna session is 13, 14 or 15 minutes, the pair realise the point is moot for anyone who doesn't go at all. The winning move is to get to the sauna once a week first; only once that's a routine four-times-a-week habit does optimising the minutes matter.
→ Action taken and a habit built, instead of paralysis over marginal details.
Common mistakes
Optimizing before you're consistent
Fine-tuning the last 20% while still doing 0% of the basics is effort spent on the wrong thing.
Is it for you?
Best for
Perfectionists and optimizers who stall when they can't do something 'properly'.
Not ideal for
Situations where precision genuinely is safety-critical from day one.
