Follow Your Own Advice...
Often I tell players things such as "practice your long tones" or "accuracy first and then speed will follow"... well, for a little bit i was struggling and some of the tunes that I've been preparing. Then it got to the point where I had to sit back and say "what would I tell a person with the problems I'm having"... and hence i had to take my own advice.
I had to practice the tunes slowly and work some stuff out and then slowly build it up to the original tempo.. It worked! my playing got a lot better.
