for me it's learning music, period. theory, different styles, etc. i don't dig learning a bunch of licks before you know how and why to use them....otherwise you'll just know certain licks you can use over certain things, with no idea who it translates to anything else. Music is a language, and you can settle for either knowing some commonly known phrases or being fluent.
I'm not against licks, we all know them, have them and use them....but it's important to know the why before you know the how.
