Teaching birds how to fly

You can't wait to start X until you have Y. You don't need to buy a course to start building a website. If you want to build something, just start. Search on Google. You don't need to learn a full programming language to launch a simple website.

Nassim Taleb wrote that humans are experts on teaching birds how to fly.

People learn to do things by doing them, not by reading or theorizing. How many books do birds read to learn to fly? How many books did you read before learning to walk? How many books does Rafa Nadal read about tennis? I guess zero; he wakes up and plays tennis. Every single day.

Your chances of becoming an expert increase with the hours you spent doing something. You might never become a superstar in your field, there is talent and luck involved in the equation, but you'll become part of the top experts.
