Practice must also be pushed. This means you have to get outside your comfort zone and challenge yourself. Most musicians want to merely “rehearse” what they already know rather than push themselves to learn new stuff (like playing in unfamiliar keys, learning bigger chords that are hard to reach or weird for the fingers to play). It’s something about harder stuff that’s boring for musicians who fall into the rehearsal trance. They feel good knowing that they can play what they know. But when it comes to playing something that’s challenging, if they can’t do it in 5 minutes, that part of the practice is over. Does this sound familiar? If so, make it one of your priorities to consciously keep practice PUSHED and watch how far you get.
