writer's block, is so much fun

I have been working on a fantasy story for a while now, and I just gotten writer's block on it. I also randomly start other little story ideas, but I want to get back to writing the main story I am working on. I hope to some day be able to continue it, even with the other stories I try to write. I do not get far in them at all, any ideas on how to get over writer's block?
