I do it like this; My songs have to tell a story. If they don't tell a story (usually NOT love, and if it is, its not blatant), then they are worthless. Writing an instrumental is a different way, completely. But anyways, then I write the solos and harmonies and things of that nature. Every musician goes through a rut in some aspect, and alot of times the rut in one area means you focus on another, and then you have to balance it out. It's pretty rare for me to get in a complete rut, i think it only happened to me once. Anyways, you can get out of a rut by doing something out of the ordinary. Alot of times, you're in a rut because you're doing "the same old ****".
