I was watching a show on the old Soviet olympic teams and I saw about how if a kid showed talent in a patricular sport he was basically forced into being on the olympic team. As with most opressive government controlled regimes most careers were chosen by central planning.
I consider myself lucky that I get to work in field I enjoy, with people I enjoy, and for an employer which is top notch.
I've had my fair share of nasty jobs, and I am amazed that we live in a country that allows you to totally choose your profession (unless it's the oldest profession ;0 )
But we can do what we want to do, and become anything that we want to be. Look at John Edwards he was the son of a mill worker (mill supervisor), and has worked hard and became a very successful trial lawyer. Bill Gates dropped out of college to form Microsoft.
The computer I am typing this on was originally thought of by two hippies who got their start building black boxes to cheat the phone company out of long distance charges.
What a country!!
