i am quite confused . It started saying good chess players are more careful and spent more time falsifying ideas but then he later gave startup examples which is the opposite ( not so careful with falsifying. Just jump into the water with conviction and figure things out on the way ) . Startup game is more like poker . It is very different from chess . Somehow the author drew the wrong conclusions. Very confusing
PS: I'm an early stage founder, who has finally some traction with my current B2B data infra SaaS. I've had a failed company in the past which had 4 major pivots, where we decided to return most of the funding to learn few things again.
