You hit the nail on the head. My last years was the easiest, stress wise, at work because I knew I could leave at any time. After making the decision to retire I would try to enjoy the job as much as possible knowing very soon I would never do this again. Walking back to the truck at the ending of the days I really observed things and had deep thoughts of the decades gone by. I would think of all the things I would never have to do again like deliver at night, dread seeing the rain storm coming, ducking when lightning struck near by, no more helpers or having a supervisor ride with me. It was a really neat time of reflecting. I would also think of things that I enjoyed over the years but as you said I couldn’t do it any longer knowing I could and was fully ready to retire.
