Wayne to be able to feel good about your accomplishments is an admirable trait. You should be very proud of all you have accomplished. People who retire healthy still miss not working and clamor for something to take up their time. I am sure you will find something that will get your juices flowing again. Perhaps you can be a motivational speaker.
For myself idle time was my worst enemy. I found depression is harder to cling to a moving target.
Congrats on all of your accomplishments and to an exciting future.
