Rubinstein believed that a foremost danger for young pianists is to practice too much. Rubinstein regularly advised that young piano students should practice no more than three hours a day. "It is not so good, in a musical way, to overpractice. When you do, the music seems to come out of your pocket. If you play with a feeling of 'Oh, I know this,' you play without that little drop of fresh blood that is necessary – and the audience feels it." Of his own practice methods he said, "At every concert I leave a lot to the moment. I must have the unexpected, the unforeseen. I want to risk, to dare. I want to be surprised by what comes out. I want to enjoy it more than the audience. That way the music can bloom anew. It's like making love. The act is always the same, but each time it's different."
