Give Yourself a Chance to Master Every Piano Piece
Problems are often caused by overestimating the current abilities and the situation of a certain piece. It is extremely good if you have a vision how the piece should finally sound and the passion to play it. But you are not probably in this state to play the piece exactly according to your wish if you need practicing. So bring the tempo and emotional tensions down to the level where you feel relaxed and in control. Find the border between chaos and your control and stay in the area where you rule. There is always temptation to rush and play with passion, but every great thing needs time and care.
