The 30/30/30 Growth Balance allocates practice time in three roughly equal parts: a third with people below your level, a third with equals, and a third with people above you. James Smith applies it to Brazilian Jiu-Jitsu: 30% rolling with white belts where he can dominate and safely try new moves, 30% with blue belts of equal ability where he must bring his A-game, and 30% with purple belts who humble him. The mechanism balances three learning modes — experimentation, contest, and stretch — so no single dynamic dominates. Rolling only with weaker partners breeds complacency; rolling only with betters erodes confidence and blocks experimentation. Distributing time deliberately keeps a learner both challenged and confident, which Smith frames as 'the hierarchy to life.'
Origin
James Smith recalls the ratio from a source he couldn't name and applies it to Brazilian Jiu-Jitsu belt levels; Chris Williamson references it as a heard concept about spending 30% of time with peers at, above, and below your level.
Core principles
- 01Growth needs a mix of dominance, contest, and humility
- 02Time with weaker peers lets you experiment safely
- 03Time with equals forces your A-game
- 04Time with superiors keeps you humble and stretched
- 05Balance across all three prevents stagnation
How to run it
- 1
Map your skill ladder
Identify who in your domain sits below, level with, and above your current ability.
Pro tip Use objective markers (belts, ranks, results) rather than gut feeling where possible.
- 2
Spend a third below you
Practise with weaker partners to safely trial new techniques and cement fundamentals without high stakes.
Pro tip This is your laboratory — deliberately attempt things you'd never risk against an equal.
Watch out Don't let this become an ego-boosting comfort zone; it's for experimentation, not dominance.
- 3
Spend a third with equals
Compete with people of similar ability where you must bring your full effort to prevail.
- 4
Spend a third above you
Practise with clearly superior partners who humble you and expose the gaps you need to close.
Pro tip Treat losses here as diagnostics, not defeats.
- 5
Rebalance over time
As you improve, the people in each tier shift; periodically re-sort them so the three-way split stays accurate.
In the wild
Smith structures his mat time around belt levels: a third rolling with white belts where he can dominate and test new positions, a third with blue belts of equal ability that force his A-game, and a third with purple belts who humble him. He calls this balance 'the hierarchy to life' and credits it with steady improvement without stagnation or ego inflation.
→ Consistent, balanced skill progression across experimentation, contest, and stretch.
Common mistakes
Only training with betters
Rolling exclusively with superior partners blocks experimentation and can erode confidence; you need easier reps to try new things.
Only training with weaker peers
Staying where you dominate feels good but breeds complacency and halts real growth.
Is it for you?
Best for
Anyone deliberately developing a skill — martial artists, athletes, creators, or professionals building craft.
Not ideal for
Domains where you have no access to a spread of skill levels, or purely solo pursuits.
