I'm in my late 30s now, after two decades as an entrepreneur. My brain was quicker at 21, memory was slightly stronger (slightly faster, easier recall), and I had greater endurance at working productively in very long stretches. And despite that, due to learning how to work more effectively, how to be far more productive with my use of time, understanding what mistakes to avoid, I'm a dramatically better entrepreneur across the board. My patience has improved quite a bit, and my understanding of how to build for simplicity, reducing things down to only what they need to be, is leaps beyond what it was in my 20s. The single most important improvement I've seen, is building up a belligerent ruthlessness when it comes to complexity and general bloat. My 21 year old self just loved to build unnecessary, complex shit.
