OP: My response to the original question--- I browse craigslist for deals on video games, books, movies, records, things of that nature. My job requires utmost attention from 8 am- 3pm, and then things rather die down, so I do often have some time to kill before I like to head home
If there's nothing there, I'll read on my desktop on my amazon cloud reader.
Or, if I don't feel like reading something like that, I'd watch a movie on amazon instant video. I'm not a "go-getter" like some of the people on this thread; I work for myself. I'm content with my salary, and workload. As long as I maintain my obligations, I'm perfectly content.
(That last paragraph was included so that I'm not told off by other people on this thread. I'm just stating an answer to OP's question, not looking to be heckled.)
