My girl, you are very talented. You could be a pianist, a good one. But the early training of a pianist, such a pianist as you would want to be, must be something tremendous. He must have had no other life than music. At your age he must be the master of his instrument.
Nothing can ever take the place of that first training.
You know very well that your technique is good, but it is not remarkable. It will never overtake your intelligence. You have a fine power of work, but you are not by nature a student. You are not by nature, I think, a pianist. You would never find yourself.
