The first time I retired, I was in my 40's (Psychologist). I had enough money and income to live modestly. I started a couple of part time businesses (horse related) and worked about 10 hours per week. I took a week off every month.
A few years ago, my wife became ill and I retired fully. I've never been so aware of the clock, not the time of day but the number of days left. I don't feel a great urgency to get anything done since I think I've already "been there and done that". My wife is one of those walking wounded. You'd never know she was ill to look at her and she could stay this way for decades or she could catch a cold and be gone. Our hobby involves traveling, no place special, just someplace else. We go to NOLA, a couple of times a year. The people are nice, the food is good and the music is free.
The psych in me advises that anyone planning to retire have an occupation/hobby in the works before you stop working. Otherwise, it's like pushing your canoe out onto the lake and looking back to see your paddle on the shore. Your new life with dictate what you do, as long as you decide to do something. Keep a student or two until you find a new obsession.
