If you could choose whatever way you wanted to make a living, what would you do? (If you're retired, pretend that you still had to work)
How does that compare to what you have been doing for a living?
If you aren't doing it, what got in the way? (education, opportunity, lack of knowledge of the possibility, lack of maturity, parents, somebody else's expectations for you, lack of natural talent, it doesn't pay enough to live on, it would require living in a place I don't like, or whatever)
