Who's made a major career change? I'm 32, have not liked my job for the last couple years, and have been coming home really angry lately. I want to switch from my nice, well-paying marketing job to something in the fitness industry, where my true passion lies. Unfortunately those jobs are relatively low-paying.

I'm afraid to make such a drastic move because of the money. We can definitely live on my husband's salary...but still...

Any words of advice?
