As a former Guitar Teacher The most important thing I tried to teach my students was Playing the guitar is not a competition. You are not competing with other guitar players. You are learning to play like you. The skills you learn at first are building blocks to help you develop over time. Some take to it faster than others but with practice and time you can learn to be a musician. You have to ask yourself why do you want to learn to play an instrument? If it is to show off then stop and realize you can train a monkey to impress a crowd with a few tricks. Real music is made from what is inside you. Just keep playing and one day you will realize you are getting better.
