frustration is a unwanted friend

i have been looking at the same set of notes for over a hour and can't find a way out of the mental circle of doing nothing with words that mean something. it is so frustrating to know that i should be coming up with new ideas or at least writing out more of a systematic theory but its like staring through a clouded shower curtain—vague forms, unable to push forward. something needs to give, though i don't know what.
