Leaking the advantage of age

I am somewhat hesitant to roll over another year. Saying "for what its worth, this is what I think" at my age is pretty advantageous. Based on reactions, there might be a limited amount of people who want to do exactly that (at any age) in a business environment.

I'm willing to be wrong. And I'm willing to learn. Is that confidence? Self-assurance? I've heard people say that some are afraid to stake a claim. Thus any success that I've had may be soley attributed to the fact that I can say, "given these assumptions, here's my opinion. And by the way, I might be wrong."

At the end of the day, if I am, there are people who might caveat that I'm only 23. At 24, it feels like a little piece of what makes possibly being wrong acceptable, fades away.
