Decide Once applies software's DRY principle—do not repeat yourself—to recurring life choices. Find decisions that recur, have little upside from variety, and consume disproportionate attention. Choose an acceptable default, encode it as a rule, and reuse it until a scheduled review shows it no longer works. Martell uses standardized meals and a consistent blue-shirt uniform so he does not repeatedly spend attention on lunch or clothing. The saved capacity is then available for difficult, high-return problems such as helping a company grow. The framework is selective rather than ascetic: remove variety only from areas where it offers little return, preserving it for experiences and decisions where it matters.
Origin
Martell connected his standardized meals and clothing to the software principle DRY, explaining that he prefers to make recurring low-value decisions once.
Core principles
- 01Repeated low-value choices consume finite attention
- 02A reusable rule can replace recurring deliberation
- 03Variety should be spent where it creates value
- 04Standardization supports harder strategic thinking
How to run it
- 1
Audit repeated decisions
Notice choices that recur daily or weekly and estimate whether fresh deliberation improves the outcome. Focus first on frequent, low-return choices.
Pro tip Review a week of calendar entries and routines.
Watch out Do not standardize choices whose consequences materially change each time.
- 2
Choose a good default
Select one acceptable option that supports current goals. It need not be perfect; it needs to remove repeated evaluation reliably.
Pro tip Choose a default that is easy to source and maintain.
Watch out A default that damages health or performance is false efficiency.
- 3
Encode the rule
Turn the default into a clear rule, recurring order, uniform, or delegated instruction. Make execution require little or no new thought.
Pro tip Automate replenishment or preparation when practical.
Watch out An ambiguous rule recreates the decision it was meant to remove.
- 4
Spend attention deliberately
Name the valuable problem that receives the reclaimed mental capacity. This keeps standardization connected to a useful outcome.
Pro tip Place the high-value task in the calendar before the saved time gets absorbed.
Watch out Efficiency without a destination can simply create more low-value activity.
- 5
Review periodically
Revisit the default on a fixed cadence or when goals change. Keep, update, or remove it based on current evidence.
Pro tip Review monthly or quarterly rather than every day.
Watch out Do not let an outdated default become an unquestioned constraint.
In the wild
Martell wears a blue shirt when shooting content. The uniform removes a recurring wardrobe choice, supports consistent visual recognition, and lets him direct attention elsewhere.
→ Clothing becomes a reusable rule rather than a repeated decision.
An operator selects a nutritionally appropriate meal rotation for four months and arranges preparation in advance. Lunch no longer requires daily browsing, ordering, or debate.
→ The operator saves time and attention while maintaining the chosen nutrition plan.
Common mistakes
Standardizing high-stakes judgment
Decide Once is for recurring low-return choices, not decisions that require updated evidence or careful individual review.
Saving attention with no target
Without a named high-value use, reclaimed capacity is likely to fill with more trivial activity.
Is it for you?
Best for
It is best for people whose recurring choices about food, clothing, scheduling, or routines crowd out higher-value thinking.
Not ideal for
It is not ideal for consequential decisions where new evidence, safety, or individual needs require fresh judgment.
From the transcript
“I just get rid of decisions I don't need to make anymore and I think that's one of the best habits you could possibly do…”
“in life I like to make a decision once this is what I want to eat for the next four months and I'm good”
“don't put your energy in areas that don't need no Roi”
