How to practice sight reading
What you learn when you are playing or practicing piano depends on how you practice. If you practice sight reading in a sloppy superficial way you will probably experience little progress and feel a little disappointed with your progress. When you realize that the results and your progress depends on the way you have practiced you will probably not become too discouraged as you will gain hope that you are able to change your progress by changing the way you practice!
