Caffeine
If coffee were run through IVs, I would probably be hooked up to one 24/7. I can't survive without caffeine.

Swearing
I could probably make a sailor blush if I wanted to. Actually, I think I have.

Procrastination
I don't see a problem with this, but not everyone seems to agree.

Twitter
It's taken over my life.

stumbleupon.com
I spend way too much time on this site.
