I know you treasure the music you follow. The music from the past by others who created it and made it part of your present (the future to them). You can learn to play! It might help not to emulate others. Your teacher’s comment is in the context of emulating others. Pick up a guitar and be happy emulating your inner music. It's there in your writing, and it shines through. You can channel it through a guitar at your pace, in your time. Your melodies.
