Getting past that wall.

Most important thing, don't open a DAW until you have an idea of what you're going to do

only bit i cant agree with, everyone has different ways of working though...some of the most rewarding pieces ive done have sprung from just grabbing things you would never think would go together...like an improvisation

I don't mean like have an idea for a song, could just fancy playing with a synth or something. I guess just have a reason to open it before you do, rather than open it and then try and find something to do.

In my experience, I would definitely agree that collaborating with someone else really motivates you. I've been making stuff for years on my own, with varying success, but until last year when I started working with a friend I never had the energy or the urge to really finish a lot of stuff.

In the last few months I've multiplied my energy and output. You could put it down to these things:

You really want to finish something because you really want to share it with your buddy
You both work to deadlines such as your next meeting/rehearsal
You get lots of inspiration and ideas from someone else's creativity (and vice versa)
You learn a lot

In my experience, I was really inspired by my friend's ability to finish tracks quickly and share them. He says that he learns a lot from me technically, which surprises me, but it's good to know it's a two-way street.

One other thing: put aside lots of time just to devote to music. Actually MAKE time and refuse to compromise. Nope, not going to the pub on Monday, Monday is a music night. Or something.

Good luck OP.
