What to do with my working Life.

I'm 36 years old with a degree in PE Education which I have been told by more then one business that I'm to fat for my degree, and even more didn't say it but there actions spoke louder. I have been away from the blue collar work since John Deere and now working on my second day care company in 7 months. Day-Care has ton of positive but also negative- IS this what I want to do with my life? That is the question I need to answer. I can't even seem to get a simple forklift job any more.
