Well, the title says it all.
What do you want to be when you grow up?
What do you aspire to do with yourself and your career when you're older?
Me? I'm happy working for a large tech company at the moment but I always throw around the idea of starting my own business related to web-application development. And if I won the lottery or had some other means to be supported so that I didn't have to work for a paycheck I would like to start a non-profit web-application/website development company that develops web apps and websites for free for other non-profit groups.
