When I was younger I went through wanting to be a vet, a ballerina, a nurse, a teacher, a police-woman and most other careers!
I don't really know what sort of job would be the perfect one for me. But here are some things that would be nice:
Challenging, but not all consuming
I could work from home if I wanted to
Allowed me to see the world
That doesn't really help me much, only reinforces the sense for me that I have no clue what I want to achieve in life!
