Here’s a few of mine:

-Skateboarding

-Writing (books, plays, puppet shows, greeting cards, etc.)

-Learning Linux

-Writing and performing rap

-Petting cats

-Repairing video game consoles and controllers

-Decorating (using things you own or spending very small amounts)

-Cooking, baking, etc.

I also enjoy putting on some music when I have to do stuff that isn’t fun, like laundry, washing dishes or cleaning.
