Good motivational read, but as someone else pointed out full of Survivorship bias. Def, much more failures than successes. The story about the 15–20 year span, worked out for maybe 1%, but its ignoring the ones who failed and ended up worse than their colleagues. I still believe that start ups and taking risks is important for growth, but don’t be the ones who become depressed and bitter if it doesn’t work out. Enjoy the experiences and the lessons learned.
