I love working at home. I can concentrate so much better than in the office, where I get distracted all the time. Office is great for meetings and discussions, but when those are over and I really need to get things done, I work better at home.

Then again, I've always been pretty comfortable with internet-based communication, so I don't tend to get lonely at all.

Also, working at home doesn't mean sitting in the same place all the time for me. I sometimes go to the park, or other places, for some change of scenery.
