How did you decide what you wanted to do for a career of 30 to 40 years?

Answer 1

Nobody does the same one job for 30 or 40 years. 

Answer 2

The career I really want to do does not have many opening spaces. Therefore, I am in a career which requires few skills and a few areas for promotion. In a few years when I turn 30 I will probably change to another career.

Answer 3

I eventually got a decent job and stuck with it. Just worked out that way. Not my idea of a good time, but I have to live . It's not  what I  wanted to do, but it could be a lot worse.
