Sounds like me when I finally retire in a few years ...
I retired at 68.5 yrs. Been retired for 6.5 yrs.
Believe me, I think I work harder now than I did then. It seems like the days just fly by. There is always something to do. But, the nice thing is that there really is time to contemplate what you want to do so you can really enjoy doing it.
You will do well once you reach that time.
