Lessons

 If one is good at taking (painful) lessons and learning from them, than one could argue it is better to do mistakes early in life than later. Early mistakes typically have a lower cost and one has a longer period to enjoy the benefits of the lessons learned. And it might be one would do that mistake anyway, so… maybe the sooner the better?

The big caveat here is right at the beginning. “If one is good at taking lessons and learning from them”. How is each one of us engineered to learn from our mistakes and keep on getting better? If you want to constantly improve, then keep this under check, please.
