Quit work or not -- the first choice

I think about aging and not using up my last years carelessly. I’m going on 68. Maybe I have 15 good years left until I start to fall apart. I cannot waste those years by staying at a job that leaves me no space for a life. I have a long list of people and things I’ve put off doing because I don’t have enough time to do them. That has got to stop. I need to make the time. I need to free up my time. Life is too short. My end of life time is too short. I need to live the time I have left so that I feel fulfilled and productive but not at the beck and call of a company. That is the balancing act I have to pull off. That is the choice I'm up against.
