I understand burnout as well. It was largely why I retired at 60. Decades of working 50 – 60 hours a week and never being fully off duty had worn me out mentally and emotionally. The Blackberry was always with me and the laptop went on vacation with us. Throw in a couple very difficult personalities at work and I said I can’t do this anymore. Life is too short. I still do a little Per Diem work for them but that is more task oriented and usually stuff I can do from home on my own schedule.
