Are you an active listener?
What inspired you to take up an instrument? I assume your answer is to pass the time or just a stress buster, and you may discover the key to your true potential of playing an instrument is knowing what you want to play!
These days with so many resources available online. It takes one click to listen to some of the best on the planet and instantly get inspired or motivated, to establish a direction and practice fervently with a goal rather than just noodling around and understanding what your instructor says should be done.
What did you like about the song? How technically brilliant was the performer? Close your eyes and listen rather than being swayed away by dextrous movements.
Maybe you'll become the next best and one day say that it was because of that Pianist or Guitarist that I play so well now.
