I have a mental list of two/three things I would finally get to do once life's craziness subsides.

1. Buy a bike, and ride around town
2. Learn how to play guitar, finally
3. Learn how to paint portraits

It's not like a bucket list. I won't be unhappy if I die without having accomplished them, but I've gone back to these three things so many times, I am convinced that they are important to me regardless of my age, state of mind, and the time of the year.
