I only ask because I started doing something similar a year ago and I've thought that for all of it. Is there any advice you can give other than "wait until you can't take it any longer"?
there are plenty of things you can do, and try. i was never totally frozen, but almost everything i did felt like some kind of test or learning experiment. also did a lot of analysis, and just a lot of listening to music and watching things as well, just taking it all in and pretty much getting my mind blown all the time, and learning new things, which didn't help stop my own ideas and goals from constantly exploding bigger and broader. you might argue that 2009 was when i said 'i can't take it anymore' and started writing like crazy. but it was all writing and almost no recording. then i gradually inched my way into recording in about 2010, but then started writing 10 times more. basically i ended up leading myself into a place where i felt like i had already done centuries worth of work, but yet none of it was finalized or realized. there were many different times where you might say it 'all started' but each one was just another step. i'm not sure if that answers your question
