I've been on a creative blog recently aswell. I keep trying though. I probably should take a break some point.
I find listening to loads of different styles of music helps. Recently been getting into hardstyle, thanks to PandaKore ;) and it's got some ideas popping up. The only problem with that is, I have no idea how to create that style of music.
Do something exciting with your life. Go out, meet people, go to life shows, stuff like that. Something I need to do more of. Not that I'm a full-on house worm, but my life is really boring at the moment. That might be causing it. :(
