Has a music teacher ever burst your bubble? Made you feel like crawling under a rock and make you doubt yourself as a piano student? This is my experience "relived" on YouTube to encourage you to keep practicing. Your day will come ... la, la, la, as long as you keep working. You didn't give up because one person in whole universe underestimated your self-confidence, did you? The day will come when friends and other teachers will hear you play and say congratulations! Great job! "Your performance was the highlight" of the evening/event/party. If it happened to me it can happen to you when you just keep practicing and finding ways to improve. Doors will open to even greater performances that may include job opportunities. Believe in yourself. Success will be yours as long as you stay motivated.
