Hard Thing Rule
Everyone must do one hard thing they chose — no quitting mid-season
The Hard Thing Rule is Duckworth's family practice for developing grit. Three components: everyone must do one hard thing requiring deliberate practice, everyone chooses their own hard thing, and no one may quit until a natural stopping point. The rule teaches grit fundamentals — choosing something interesting, committing when difficult, and seeing commitments through.
The genius is its balance between autonomy and discipline. By choosing their own hard thing, people develop the passion component. By not quitting mid-season, they develop perseverance. The rule normalizes struggle and teaches that discomfort signals growth, not a reason to stop. Duckworth uses this with her own daughters and reports it as one of the most important family practices they have.
- Everyone must do one hard thing requiring daily deliberate practice.
- Everyone chooses their own hard thing — autonomy feeds passion.
- No one may quit until a natural stopping point.
- Adults model the rule alongside children.
- Each Person Chooses Their Hard ThingEvery family member (including parents) selects one activity requiring regular deliberate practice that they find genuinely interesting. This could be a musical instrument, sport, language, or any skill-based pursuit. It must be challenging enough to require real effort and self-chosen enough to sustain interest over the commitment period.Pro tipLet people explore several options before committing — the choice should be genuine.
- Commit to a Defined PeriodOnce chosen, everyone commits to a natural stopping point — end of a semester, season, recital, or tournament. This prevents quitting on a bad day while allowing direction changes at appropriate intervals. The commitment teaches perseverance through inevitable low points of any challenging pursuit.Pro tipDefine the commitment period clearly at the start.WarningDo not make the period so long it becomes oppressive — one semester or season is usually right.
- Practice the Hard Thing RegularlyEngage in deliberate practice on a regular schedule. Show up even when you do not feel like it, work on specific weaknesses, and seek feedback. Regularity matters more than duration of any individual session. Parents should visibly practice their own hard thing to model the behavior for children.Pro tipKeep a visible calendar marking each day of practice.
Angela Duckworth describes how she and her husband practice the Hard Thing Rule alongside their daughters. Her daughters chose violin and ballet, while Duckworth herself chose a challenging yoga practice. Each family member practices regularly and cannot quit mid-commitment even when frustrated.
Duckworth developed this rule for her own family when her daughters were young, drawing on her research findings. She wanted a practical daily way to instill grit qualities without lecturing. The rule was inspired by her observations that the grittiest people she studied had all committed to a hard thing and seen it through. She shared it in her 2016 book and Talks at Google presentation, where it became one of the most cited practical takeaways.
