Until your home computer breaks you'll have no idea how much time you waste on it.
My computer hasn't been able to connect to the Internet for two weeks. In those two weeks, I've gone to the gym regularly, read 3 books, reworked my resume & cover letter, donated clothes to Goodwill, enrolled in a class at UCLA, watched less TV, and gotten more sleep. The Internet isn't a bad thing, it just makes it easier to get side-tracked.
I sit at a computer all day at work. It's nice to come home and do things like prepare my own dinner, enjoy a glass of wine, and go for a stroll. I'm sure I'll have my machine fixed soon enough, but I'm gonna try to keep this thing going for a while. My goal: be happier with less. It's nice to disconnect.
