Burnout is a very important topic; thanks for writing about it. For some strange reason, I have observed that men tend to get burnt out more than women. Perhaps, we throw ourselves at work and try to live up to the perceived standards of a responsible man. Or perhaps, women are incredibly stronger beings.
It's great to read how you tackled your situation Steve, and managed to turn things around. I believe the first step in solving a problem is acknowledging and accepting the problem. I had been good at ignoring problems and putting up a face. As I have gotten older, I care less about what others think and more about what makes me happy. Rewarding oneself and mixing it up are vital. It's hard to let something overwhelm us if we are doing different things. As the old adage goes, variety is the spice of life.
