Kobe Bryant

Who they are

Kobe Bryant (1978–2020) spent 20 seasons with the Lakers and built a reputation on an almost pathological commitment to craft — the "Mamba Mentality." He's a reference for founders because the work ethic was not about hours; it was about the obsessive, compounding pursuit of being slightly better than yesterday at the things that matter most. What he made look like genius was actually deliberate practice, repeated past the point most people would stop.

Core Ideas

  • Mamba Mentality — obsessive, private commitment to getting better
  • Deliberate practice over volume — quality of reps, not quantity of hours
  • Care about the details no one else notices
  • Jeff Bezos — same long-horizon, craft-obsessed operating posture
  • John Collison — contemporary version of the same ethic in software
