But how much?

Do you believe that 'if you do what you love, the money will follow'?

According to Parade Magazine's annual 'What People Earn' report, it's not necessarily true. For some people, in high-profile careers, yes. Justin Bieber earned $55 million last year. Serena Williams made $19 million. Paula Deen cooked up $16 million.

Then there are the people like Martie Anderson who earns $12,000 as a pet-sitter, and "loves being her own boss"; or Lynn Kata, who was hooked after her first Zumba class and now earns $24,000 as a Zumba instructor.

Maybe their motto is 'if you do what you love, you'll never work a day in your life', and the money doesn't matter.

Then I wonder about people who earn a good salary, maybe a great salary, even an outrageous salary, but they hate what they do. Does money compensate for being miserable at work every day?

Here's the What People Earn report (fascinating to see the range of salaries and jobs), complete with career advice for different stages of life.
