I am a feline fiend, a contented mew, and i read lots of book
Books. My head would EXPLODE!
Arty or crafty things. I get frustrated and depressed when I'm not making a thing.
Cooking tasty meals for people I love. This makes me happy in many ways.
Talking nonsense and hence putting the world to rights with my friends.
The internet. Sad but true. I rely on it for job and yarnshop and conversation and information.
(this list does assume i have by default food and shelter and warmth, btw)
