Jake Humphrey relays Matthew McConaughey's phrase “don't leave crumbs” as a rule for decisions at any scale. A crumb is an avoidable consequence left by a present choice that must be picked up later through regret, apology, delay, or extra work. The mechanism is a brief downstream check: identify what the choice could leave behind, imagine the later cleanup, and remove the preventable cause now. Humphrey applies it to alcohol, choosing clothes in advance, and his own rushed preparation for an interview. He also stresses that people discover their recurring crumbs by making mistakes, so the framework is not a demand for perfection. Each failure becomes evidence for the next preventive adjustment.
Origin
Humphrey attributes the phrase to Matthew McConaughey and explains it on The Diary of a CEO.

How to run it
- 1
Define the choice
State the immediate decision and the result you want from it.
Pro tip Include small choices that can affect tomorrow's performance.
- 2
Scan for crumbs
Ask what unfinished task, regret, delay, or repair this choice could predictably create later.
Pro tip Use past mistakes to identify your common blind spots.
Watch out Do not pretend that every consequence is foreseeable.
- 3
Remove the preventable cause
Change the choice or prepare one thing now so the likely cleanup does not arise.
Pro tip Prefer a small preventive action over a complicated safeguard.
- 4
Learn from residue
If a crumb remains, record what created it and use that evidence in the next similar decision.
Watch out Treat the mistake as feedback rather than proof that the whole method failed.
In the wild
Humphrey began shaving shortly before a major interview, then discovered he was late, on the wrong Wi-Fi network, and unable to find his questions. He presents the episode as a collection of preventable crumbs that exposed his recurring lateness and preparation weaknesses.
→ The mistake supplied specific evidence for preparing earlier and checking logistics before future interviews.
Common mistakes
Looking only at the immediate reward
A convenient choice can look harmless until its delayed cleanup is included in the decision.
Demanding perfect foresight
Humphrey says people learn which crumbs they leave by acting and making mistakes, not by predicting everything in advance.
Is it for you?
Best for
People making recurring operational or personal decisions with predictable downstream consequences.
Not ideal for
Complex choices where uncertainty cannot be reduced to a simple preparation check.
