I think 99 meant 5:00 PM. But never mind.

The trick is to have at least several projects you want to pursue and to take steps to do one thing about them at a time. Find a teacher or make a list of long-deferred books, or take up skeet shooting ore whatever you have never had time for. Even though you are "retired" you still have to manage your target list for the day; the Great Thing is they are your own targets. :D
