Have I learned more failing a startup than making it BIG?

Today's one of those days for me where you look back in the past and wonder where you would be and what you would be doing if a previous startup had made it BIG. You would be managing a team of rockstar programmers, amazingly talented designers, or so to say the cream of the crop of any team. But do we at that point stop improving? With a startups that's made it BIG, you spend your time learning all the ropes of managing it, and that doesn't really give you time to continue building your skills. If you're a programmer and your startup takes off, you might no longer work on anything that used to challenge you in the past. You would be working on parts of your project that were small or insignificant so that your team of rockstars would do the heavy lifting. DO we at that point stop improving?

While I'd love to have amazing success with my startup, the thoughts frighten me sometimes. Once I reach a level with my skill to be able to create something that people will use, that's where I'll stop because I'm comfortable with my progress. But that stifles innovation and improvement. I spent part of the day today going through my bookmarks and going through some of the role models that I've looked up to before for their skill. But a year later, they're still at the same level. They're no longer as interesting as they used to be and I've moved on to new people to look up to. Have I learned more due to my failed startup than if I were to make it BIG? Let me know your thoughts
