Enjoy your time and don't feel like you have to fill it with stuff to stay busy. Read a book. Watch a movie. Meet up with friends. Travel. Go to bed when you want to and get up when you feel like it.
Enjoy your retirement!

And do you know what? If you decide that you feel like you need to do something more then do it. Take a class, take a walk, take a stand. Whatever you feel like doing without having to justify or report to anyone else.

Sometime people need to learn how to nap. It doesn't even have to be actual sleep. It can just be the act of being still and closing your eyes. Learn to enjoy the restful time. You have earned it and it will rejuvenate and strengthen your mind and body.

You can choose to do nothing some days. Just enjoy the day and see what it brings.
NAP. Nap whenever the mood strikes you. It worked for you when you were a little kid and it can work for you now.

Yup. Y'all are looking for what you are going to fill your days with. You don't have to fill your days. You don't need a schedule. You do not have to "produce" anything. You are RETIRED.

He had me at hello. Damn.
