As I've said countless times before, it takes YEARS of hard-core study and practice to play anywhere near like a pro musician.
You won't figure any of this stuff out in a day or a week or even a month.
Years.
Years and years.
And really this stuff is not complicated at all IF you've put the time into learning it. It IS all shapes and patterns and numbers and memory and so forth, which gets combined with our own personal attitude and character and technique, all of it taking years to develop, and then *poof* you might play like a pro...but you'll still have to practice.
I still practice and learn new things even though I've been playing for 34 years.
