01
Find the real problem before designing
→ the wrong question wastes everyone's quarter.
02
Iterate in tight loops with real users
→ five conversations beat fifty assumptions.
03
Build systems that scale, not just screens
→ tokens, patterns, and rules a team can defend.
04

→ if we can't measure it, we shouldn't ship it.
05
Never stop improving
→ the design ships, then the work begins.
