Learning and Happiness

I've been thinking about what makes me happiest:
Outdoor adventures, certainly.
Reading books.
Teaching classes.
Playing board games.
Talking to interesting people.
What do these things have in common?
Learning.
So, let's take outdoor adventures. I really enjoy them all, but they really sing to my soul when I go new places or learn new skills.
Or let's take board games. One wouldn't think they're a learning experience (and sometimes they're not), but, again, they're at their best when I discover new strategies or ways of seeing them.
Or, crossword puzzles, which I've decided I love. I learn new words, new associations, new ways of thinking.
I hope to dedicate my weekly blog to stuff I've learned. Maybe a daily Facebook post on what I've learned too.
