If I were a child, I would try to post this video in as many TFP threads as possible.
I never became a firefighter. I'm happy with the way that one turned out. I never played guitar in a rock band. I'm not too upset about that one.
However from age 14 to about 19, I was convinced that I was going to be an Olympian. I never even made it to the Trials without paying for a ticket, though. That one still smarts, enough that I've already caught myself evaluating my sons for signs of athletic talent and where it may lie. Max might have the makings of an excellent distance runner. We'll see if that's what he wants to do, though.
