There's something to be said for an organized practice schedule. By the same token though, if all you're doing is running scales, modes...etc, it can get a little dry. I've tried to mix it up. Do some of the things that I find a little dull and then I throw some things in that I like to do...It seems to keep me moving.

I'm trying to learn a new technique or chord or something every month. That's my challenge. And then when I practice, I have to go back through and keep working at the stuff I've already been doing.

I dunno. It seems to be working for me. I guess it's a matter of preference.

(As far as theory; I find myself trying to learn it because it just seems so inconcievable to me. I love a challenge).
