In learning a musical instrument, I have come up with "The Three P's" for you to remember if you want to master your instrument faster.
Listen and give your instructor your full attention when you're in class. Bring a notebook and pen and jot down any information, tips or advice your instructor has that will further help your music playing. Ask your instructor if you have any questions or point of clarification.
Learning an instrument is hard at the beginning so you must be very patient with yourself. Don't be discouraged if for the first few months you feel you're making slower progress than the rest of your class. Each of us learn differently and it doesn't necessarily mean that if you learn slower you're not as good as them. Stick to your lessons and you'll be surprised at how much you've improved in the end.
Ahhh, every music student will hear this saying, "Practice makes perfect." It's true, the more you practice playing your instrument, the better you become at it. Set a time each day for practice and discipline yourself to stick to your schedule. You'll see, in no time you'll be playing beautiful music and you'll be pleased with the progress you've made.
