Even with solid validation, do you still feel uneasy about moving forward? Like you're taking a wrong step?

I'm a web developer, and I started casually writing blog posts and articles about a year ago, just building up an audience over time. Over the past couple of months, some of these posts have kind of taken off and have gotten me a decent following on social media and through my email list.I decided to try and capitalize on this and pump out a course in a niche area that I write about. I priced it for $19 and so far in the month of February I've sold $5k worth.I think I want to go all-in on this as my side income, and maybe work up toward replacing my full-time job with it. Continuing to produce content for free and then making paid courses on specific niche topics that get the most traction. I've seen others go this exact route (Wes Bos, Kent Dodds, Brad Traversy), but I don't know if I'm good enough and ready to do this, even with this validation.I've always been hesitant to give my full attention to something because I feel like another path could give a better outcome, even with that $5,000 staring me directly in my face.Anyway, I'd appreciate any thoughts or anecdotes about this! see hubwealthy.com/wealthy
