Eric Siu explains why he abandoned a fitness blog and argues for staying in your circle of competence. He tried to build a fitness business despite having no real expertise, and it failed. The lesson: don't chase opportunities outside what you actually know.
Don't think that you can just go in any industry and really— like, I thought, oh, maybe I should start a fitness blog because I'm clearly very good at blogging. Oh, really? I did, and it failed. That's why I never talk about it. I'm like, man, I could go in any space, make a blog, and go. So I'm like, you know what? Fitness. Fitness is huge. I should go in fitness. Bust. So you have to stay in your circle of competence. I think that's very important.
