Learning an instrument, no matter what it is, must come from within you. The music and style you show comes from your heart and soul. If you have no desire to learn and succeed, it will show in your playing.
Experience is also an important aspect you should take into consideration. If you can find a piano teacher who is recommended by someone you know, then you will assure you are going to learn the right way. Moreover, the teacher has to be quite supportive in order to encourage the student to learn and accomplish more. Where the teacher dwells and his proximity to your house is also important when you choose the piano tutor.
If you can find a good piano teacher who dwells in a house next to you then do not hesitate to hire him. You ought to evaluate the cost of the tutor. The more experienced the teacher is the more he/she would charge for his lessons. However, the piano teacher's cost should be calculated reasonably.
