2) The Internet
I may get a little bit of a “pass” on this one, because it is the crux of my job…but I find myself unconsciously checking my (7 different) email accounts throughout the day…as well as a several blogs and sites. Like an obsessive-compulsive who needs to shut the front door 42 times before leaving the house, I will roll through the sites I have logged into my memory throughout the day, almost as a compulsive catharsis.

3) “Completion”
Whether it be completing a collection of “widgets” or knowing everything there is to know about a specific topic…my mind constantly races until I feel like I have every last detail in my head or worked out on a specific project. (This is especially dangerous for me as a Web Developer…since no website is ever “complete”)
