Well, I'll be sure call on you when I need expert advice. After just one month of being ungainfully (and happily) unemployed, I cannot figure out how I ever had time to work. This is a good sign, no?

For the first few years, I woke up every morning thinking to myself, "I'm on vacation!"
The thing I like best is not having to go out when the weather is miserable.
I also noticed that I had as much written in my little pocket calendar as when I was working, though admittedly, many of them were records of which restaurant(s) I'd eaten in each day. I felt the same as you: "How did I have time to work?"
Have you set yourself any goals for your retirement? I had two: clean my house, and finally compile my birding life list. I did succeed in throwing out a lot of papers in the first 6 months - I've never done the life list. I'm too busy!
One of my friends - much more productively active than I - has a rule: get out every day to do something - movies, museums, theater, gallery openings, sports events, exploring a new area of the city, a hike - choice is up to whatever you're interested in.
