So we can also say that if we believe that we can succeed in one thing, we are more likely to believe that we can succeed in another. All too often I have had students (of all ages) tell me that something is just too hard for them. And often, this is a running theme for these students. A new technique, a memorization request, a more difficult piece of music, learning to use the sustain pedal--these are all "too hard".
The first and most basic way to start practicing away from your instrument is to adopt a new and improved outlook! This is also a technique used in cognitive behavioral therapy, in which we learn to notice, challenge, and change our damaging/unhelpful thoughts! The first step is to just notice when we have a thought that something is too difficult for us to achieve--and to try to notice this thought without judging it (or ourselves)! The second step is to challenge this thought and see if it is correct. In other words, have there been times in your past when you have thought something was too hard and you achieved it in spite of that? And the third step is to change our thoughts--this we can do by replacing our negative thoughts with a positive alternate. For example, instead of thinking "this is too difficult", we can decide to replace this with "this will be a challenge, but I will be able to do this with some work!" After a while, this will become a more common way of thinking!
How we approach our life will be, for the most part, how we approach our music--at any level and at any age!
