With Huberman's invitation to 'kill the 10,000-hour rule,' Wood clarifies that the Ericsson violinist study measured how much expert violinists had practiced by age 20 — they weren't experts yet, and 10,000 hours was an average, not a prescription. The more interesting finding from that study is that these violinists organized their practice into two sessions of 60–90 minutes per day, which Wood argues represents a practical upper ceiling for genuinely effortful skill work. He then introduces the 'thirds principle' from athletic training: in any sustained learning endeavor, roughly a third of sessions will feel great, a third average, and a third awful. This framing is corrective — the glorification of flow creates an expectation that high-quality learning should always feel good, which causes people to interpret bad sessions as signs of failure rather than necessary variability. A pianist study is cited to support the importance of sustained practice volume for maintaining fundamental skills, with Wood noting that practicing complex pieces often implicitly incorporates the fundamentals anyway.
Elite performers know that a third of training sessions feel great, a third are average, and a third are terrible — and that's normal, not a sign of failure. Expecting learning to feel effortless all the time is what gets people to quit.
