Here is what I have been doing and how it's going:

- Chess - I always knew how to play, but challenged myself to really learn the game and get "good". I have a friend who I used to think was unbeatable. I've beat him twice now!

- Woodworking - not traditionally an intellectual pursuit, but you develop skills and craft something cool. I started making a board game in December and I'm about halfway done.

- Learn the ukulele - I am a cheap ass so I've been looking at and pricing out ukuleles for months now. I finally bought one and will do my first lesson tonight.

- Listen to podcasts - History, politics, current events, daily news. I've learned so many cool things this past year. Also, you can listen and learn while you are doing chores around the house.

- Exercise - I lift weights and go out mountain biking frequently. For me, this is the easiest way to get out of a moody brain fog.

- Reading - I've read 2 books so far this year in 2021. Last year I read 3/4 of a book.
