Up until a year or so ago, I was a criminal prosecutor for 6 years and LOVED it.  Some of the trials were pretty stressful, but I felt great at the end when the jury did the right thing (which was not always!).  I find criminal law so intersting (you wouldn't believe some of the stuff we'd see), and it was usually a lot of fun working with my colleagues, defense attorneys, judges, police officer, victims, witnesses, and all kinds of interesting folks.  Now, with 2 young children and no family nearby to help, I find trial work too demanding, so I'm handling criminal appeals on behalf of the State, and I love this work, too.  I still deal with all sorts of interesting criminal issues, only in a different context.  And, I get to work part-time.  
I feel lucky that I'm happy with my work.  I hope those of you still searching find some happiness in your work, too.  I think it will come if you look hard and have patience.  And, in the meantime, at least you love your fitness instructor!  I'll keep my fingers crossed for everyone.
Have a great night!
