I would totally read that Princess Tutu/Yu-Gi-Oh crossover.

What's helping me at the moment is just building up a habit of writing for whatever story I'm working on every day, even if it's only one sentence. And, if you're really stuck, you can just not!fic/outline the rest of the first chapter and move on to the next bit and then come back to it when you're feeling in the mood to tackle the difficult part!

Also, hiii! :D
