YouTube is the best invention in modern history. While working I can passively listen to thousands of ideas in a year often curated by my interests automatically.
We don't teach people how to use these things well but we should.
We don't teach people how to use these things well but we should.
This is how I exercise that skill. I listen to science, sociology, religion, conspiracy theories, relationship dynamics, etc.
Sometimes, I pick up something. Most of the time I'm allowing the ideas to float around in my head.
It helps a lot to practice this skill, because I trade for a living and I need to be able to convince myself that I am wrong about something all the time.
