Frustration and errors are the signal your brain needs to change
September 27, 2026 · 25 min read
Discussions of learning, willpower, and schooling all present struggle as useful: errors open windows for neuroplasticity, and doing hard things strengthens tenacity circuits. Seeing discomfort as productive rather than as a sign of failure makes it much easier to persist.
The rules, numbers and steps worth keeping in front of you.
- Huberman: the brain changes when errors signal that something is not working, not from experience alone.
- Huberman: errors release epinephrine and acetylcholine; dopamine comes with getting it a little right.
- Huberman: the rewiring itself happens later, during sleep.
- Huberman: once errors start, stay with them for about 7 to 30 minutes.
- Huberman: tell yourself the errors are good for learning; it adds a reward signal.
- Huberman: adults learn best in small increments and when the skill truly matters to them.
- Huberman: work on one kind of error at a time; piling on new ones confuses the system.
- Huberman: flow and routine exercise maintain what you have but do not drive change.
- Huberman: do small, safe things you do not want to do; if you are eager, it will not build tenacity.
- Huberman: reward yourself after a hard effort occasionally, not every time.
- Huberman: being too anxious or too tired keeps you from learning; fix your state first.
- Liemandt: let children struggle and fail on the way to success, supported by a caring adult.
- Liemandt: treat careless errors as a missing foundation and go back to the basics.
- Disordered eating history or a health condition: see a professional before harder food or exercise challenges.
