master the guitar

I’ve been playing for quite some time now (10 going on 11 years). I love the guitar because of the infinite way to play the same chord progression. The way you can staccato, mute, fast pick, tap and slap the strings to get a sound that’s uniquely yours. True this is an ongoing goal that can never truly be obtained (hell, even steve vai can attest to that), I still want to reach a higher level of ability than where I am presently. I just want to say that I am definitely not where I should be for 10 years of playing. I haven’t practiced enough and been focused enough. Sure I’ve gotten tempo done (which you NEED a metronome, any other way and you’re kidding yourself), I’ve gotten harmonics, scales of all kinds, etc. down, but I haven’t gotten the speed, the arpeggios, good two handed tapping (I can tap, I just don’t know what to do with it and have it sound amazing), and other techniques not mentioned. Right now I’m practiced, for lack of a better term, double picking (harmonic picking?). You know that harmonic sound that really makes a guitar scream during a solo? That’s what I’m talking about. I’ve been practicing that over the past five days and I’ve seen some amazing progress. I don’t remember the last time I picked up on a new guitar technique so quickly. Anyway, after I become more proficient with that I think I’ll move on to tapping. Can anyone offer me any advice?
