Educate yourself! No matter what level you are at today, you can be and should be learning more. If you are currently studying with a teacher or enrolled in a music program at a high school, college or university, you are on the right track. If you aren’t doing this (or if you feel that your current teacher is not helping you enough in reaching your goals) I strongly recommend looking for a new teacher.
I prefer to be wise like the Buddha, and take the Middle Path. This is the one I have chosen, and I will describe it for you.
NEVER GIVE UP! Never say can’t. Never say I can’t. Never say someday. Never say if… If your IQ is higher than room temperature, if you have all of your fingers and if you really want to succeed, you can.
You should be able to play all the techniques of the guitar. Van Halen did tapping but not with all his fingers as others have done. He didn’t play finger style much either, but we still regard him as an important guitarist, the same thing can be said for Vai and many others. Classical guitar master John William’s probably doesn’t play well with a guitar pick (I am assuming this to be true, I have no proof of it), but he is considered one of the greatest classical guitarists alive today.
Skills like improvisation, songwriting and playing with a guitar pick or not going to be high on his list of skills to acquire. This is because classical guitarists generally don’t do those things – and don’t need to to be great at what they do. These players are great players in their own ways and they have spent many years developing their skills. Learning everything about guitar playing would have taken away precious practice time from the things they needed to focus on to reach their goals.
Absolutely spend a good amount of time in practicing reversing that habit. Practice in a new way, where you make sure you do what you weren’t doing before. Analyze the essence of that bad habit, extract it from it’s musical context, and perhaps make up “auxillary exercises” based on the essence of it. Use all the practice techniques that I teach to effectively begin this process of reversal.
To be GREAT means I have to be BETTER than everybody else. We already touched on this one above, but it is worth mentioning again here. What matters is reaching YOUR goals, not someone else’s goals. Who cares if you are or are not better than someone else? This is not the olympics. Music is the art of expression (or for some people, the science of entertainment).
For instance, the process may go like this: I notice I have trouble with a fast scale passage in a piece I am playing. I notice a particular note starts disappearing when I reach a certain speed. The note is being missed. I notice the finger responsible for playing that note is the third finger. It is not getting to the note because it is going up in the air in reaction to the second finger being used right before it in that particular scale passage. In other words, it is tensing in reaction to the movement of it’s neighboring finger, and I have not been paying attention to it. I realize this is a bad habit that pervades my playing, a third finger that tenses up in reaction to the use of the second finger.
