I’ve observed hundreds of guitarists over the years from all different skill levels, and the ones who are making a lot of progress often share a lot of the same traits - they have a plan when they sit down to practice, they know the people to go to when they’re facing a hurdle in their playing, and they’re endlessly curious about guitar and music in general.
But outside of all of that, there’s one habit I’ve seen that all of my favorite guitarists have - they practice active listening.
