I'm 35. I've worked for a couple small companies and I am at a startup now. I certainly hope my life doesn't end now. I certainly would love to get something started but I feel I'm old enough where I understand the value of family and sane time limits. Looking back I could see myself taking a shot in the dark on something but I'm not necessarily disappointed that I didn't. I've learned so much and continue to each day. If you want to be a billionaire by 25 you'll kill yourself. The odds are so astronomical it's almost funny. I say spend your years learning what you can, then start something when you have savvy and perspective. But that's just me.
