The process of learning to play an instrument is not always easy. It involves not only your mind but also your body. You will have to learn fingerings and/or chord shapes, develop technique, and memorize new information. Slowly, with consistent practice, you will find yourself getting better. With each new milestone, you gain a small reward for your efforts and this will keep you motivated. Making music requires patience. Instead of getting immediate results, you will have to persevere. Keep at it! you will achieve the results you desire.
