I thought for the longest time that I was going to be a veterinarian. But, then I joined my high school paper and realized I could write better than I could dissect.
Up until senior year in college, writing for a newspaper was the plan, but then I dabbled some in technical writing classes (figuring that if my brother could do it, certainly I could) and, lo and behold, some computer company offered me 2.5 times what a newspaper would, and I signed on.
Now I'm a product documentation editor and hate the hell out of it.

But, I have a fat 401(k) and hope to live long enough to enjoy it.
Seriously, I've been considering opening a bakery a lot lately. I bake all the time and can imagine how wonderful it would be to be my own boss.
