Should I sell my laptop?

I have a small income, but at the moment I am completely broke. I’ll be leaving school for break soon, which will mean no income and no money whatsoever. Craigslisting this laptop would help with that, and would also force me to limit my Internet time. I’d like to read, exercise, and meditate more, but it’s so hard to resist the computer when it’s always available. Between Fluther, Reddit, Wimp, StumbleUpon and Netflix I can spend every waking hour hypnotized by this thing.

This campus has many public computers, and when I’m at home there’s a library a short walk from my house, so I wouldn’t be completely cut off. Still, it would mean a long time without a personal computer of any kind, something I haven’t experienced since before high school.
