I came across this good post on the Gradhacker blog getting past writing blocks from an academic perspective.
The post offers six points to follow. One of them, “Do a writing warm-up,” echos a point I made about writing in one of my previous posts.
Enjoy!

Drops of Experience 
As a hobby I do post by post roleplaying. I tend to make a few posts as writing warm up, before moving onto academic writing. And if I get stuck during the day, I do another couple of roleplaying post to recharge the creative juices. It’s been helping me get rid of writing blocks most of the time since I’ve started doing that.
