Resisting the lure of Facebook

I’m beginning to think that having another break from social networking sites would not be a bad idea. Checking Facebook and Twitter is becoming one of my main methods of avoiding focusing on the writing that I’m supposed to be doing for my course. Yes, they can be a good way of catching up with people and keeping in touch, but mostly I just waste time reading people’s updates. The trouble is, when I’m at the computer and trying to write, the temptation to just have a quick look is irresistible. Maybe I just need to set myself time limits...
