the post on BoopSnoop was very impactful for me too! As a software engineer, it's drilled into your brain that you have to think about high scalability and user facing products. I used to have a lot of ideas, but the first instinct was always to build a paid user facing product. None ever got built. But after reading that post a few years ago, my mindset was completely flipped. Since then I've built umpteen tools, services, macOS menubar apps, tail scale services .. just for myself. And I love it!
