on being impatient, from the excellent book, “The Practicing Mind“:
Look at an activity such as taking piano lessons. Children can’t see the point in practicing because they have no concept of being able to play well and the enjoyment that would bring to them. That is why they get impatient. Why do it? Adults, however, do possess an understanding of the point of practicing, and it is for the exact opposite reason. They do have a concept of what it would be like to play well and that is the very reason they get impatient.
