I have been enjoying semi-retirement for 14 months now. What exactly, you ask, is "semi-retirement"?
The "retirement" part means that I left my job, and I no longer need to work. (I am using the word "work" to refer to a paid job.)
The "semi" part means that while I don't need to work, I may decide to work. If I do work, it will be by choice and not out of necessity. It will be on my own terms.
My days of
having to work are over. This means no more unrelenting stress. No more endless adrenaline rushes. No more days of back-to-back meetings when I can't get any real work done. No more days of a backlog of emails in my inbox, every one needing a response yesterday.
Quoth the raven: "Nevermore."
