Most I ever worked was 135hrs/mo, and never felt like I was working too much eventhough my wife said she felt the tension during busy weeks. I always denied it but fast forward to now where I am working 3-4 dys/month by choice and I can see what she is talking about.
life is so much better when work has become more of a hobby than a job. Docs who don't what they could do with their time just hasn't cut down to know there are lots to do. I enjoy working out regularly, playing golf 2-3x/wk, seeing my kids all the time, spending time with the wife, always some house chores, more travelling, etc.
I always thought that I would work 4-6 dys a month b/c I "did not know what to do with my extra time" but man, I am seriously contemplating working 2 dys a month just to feel like I am not completely hanging things up.
