I also agree with this observation, but it's clearly an unrealistic expectation that we should all be accomplished and nearing retirement by the time we're 30.

I'm a 22 year-old learning animal. I expect to get my ass handed to me every time I deal with someone my senior; given the experience I've had with my first start-up, I've found this to be par for the course.

While I believe that I have it in myself to build the foundation for a highly profitable company, I also expect that my ability to build great companies will only improve with age.
