Over the last few weeks, I’ve been learning about a new topic. Part of that effort has been seeking out credible people who deeply understand it. It’s not always easy to figure out who deeply understands a particular topic. I’ve noticed that finding the first person can be a challenge, but once you do, they’ll usually lead you to others.

YouTube has been a helpful source. I’ve been able to find videos of interviews from fifteen years ago up to today for some of these people. This has been an efficient way to evaluate people and learn the new topic. When I’m comfortable that someone is a master of the topic, I’ll watch as many interviews of them as possible and buy any books they’ve written on the topic.
