If weather permits, I rent a kayak or canoe and tool around on the water.
I read a lot, look at stupid pictures on the internet, and play some video games if there isn't anything going on.
As far as careers go, I'm currently working as a plastic technician at a factory. Its a blending of maintenance and engineering, without the engineering pay. I'm a hobbyist programmer, and am currently trying to break into that market as an on demand/ freelance developer.
Physical activites (running, climbing, etc)
Ender's Game (the entire series)
The Nightside Novels
Big Bang Theory
I'll watch just about any movie. I partial to horror or action / dramas, but a movie with a cute romantic underline is just as good
