Have you ever looked back after a gig and realize that you’d shot yourself in the foot, because you got the balance wrong in the practice room beforehand?
You’d focused so hard on one or two specific areas that you totally neglected other aspects that were really vital.
And it was a bit of a shock when the performance came around and those unexpected problems were revealed.
It doesn’t have to be like that ever again, though. There is a way to make sure your practice is constantly adapting to keep you focused on the most important topics.
