In a nutshell, I quit trying to explicitly plan and organize my life (not that I was any good at that) and instead I have a giant bag of things I need to do. There's usually a bunch of projects, and each has a todo list. All I do is when I have the time to work on one AND the motivation, then I go bang out as much as I can until I can't. By having lots of different little projects I'm pretty sure I'll always have something to work on that motivates me at that time.
The only caveat on this is I then do one thing at a time. I see too many people who can't get their todo list down are usually trying to do 5 things at once. A good sign you're this kind of person is if you love patch queues. Just do one thing, and make sure before you do it that you can do it. Don't juggle 10 things at once.

That MIGHT just be the secret to Zed's success -- that so much in the world seems to piss him off means that there is so much stuff he feels he needs to fix that he's constantly drowning in the need to fix something.
Some of us are more complacent -- I'm happy to fix the things that irritate me, but my body of work may be less prolific because I'm generally happy with the products that I use.
We called this process 'Hate Driven Development', and yes, in hindsight (and even in the moment) we all knew what she was doing, but she was clever enough to put it out there in ways where it worked even still.
Now that I'm just working on Mongrel2 it feels like I do less. Weird.
Oh, and just out of curiosity, what guitar music are you spending the most time on? Is it mostly your own stuff, or are you learning a lot of things written by others?
