Watercolor painting and drawing. I sold my first painting in my first show and was just stunned. I love art and never thought I'd be able to pursue it.

Congrats!! I found watercolor painting the least forgiving of paper media, so my hat is off to your mastery.
Also, my hobbies Sitting in cafes in exotic places with my Mac and doing one or more of the following:
Reading (yeah, still books, as well as surfing)
Jazz, blues (listening to it)
Drawing (still on paper)
Photoshop painting (on my Mac)
Photography
AND
Computer science (my research field, but I love researching it or reading about it); Movies (going and taking research-related video); Building doll houses (electrifying one; good practice for mucking about in a computer).
Hiking; Running (just a newbie); Pilates and weightlifting.
Daydreaming
(Used to like going to galleries and museums but since I started on computers, I feel like clicking on most paintings on museum walls and waiting for the screen to change)
Would love to learn astronomy
