Not really. The key was to find a niche that worked. He “Got Started” with tools he wanted to build and it didn’t work out. It wasn’t until he pivoted to identifying trends, building an audience, and building tools for them which he could market to his audience that he found success.
He's saying to just get started, and you will figure it out. So when you're arguing that "trends", "audience", etc. is what lead to his success, yes, that's what it means to:
1. Get started (just start, and improve) 2. Become better and learn (whether that's finding trends, building audience whatever)
Many paths to success, so the lesson isn't specific in many cases imo. Hence, why arcbyte's comment is really good imo.
