Strategies for monetizing personal expertise in a niche hobby
I've been seriously into restoring vintage electronics for about 15 years now and I've built up a pretty solid set of skills and knowledge. I have a lot of specialized tools and a dedicated workspace. I'm wondering if anyone here has successfully turned a really niche hobby like this into some passive income. I've thought about maybe creating some online courses or perhaps selling restoration guides. What are your thoughts on this approach?
