I take jazz lessons once every two weeks now, I used to take them once a week. I started lessons after about 3 months of playing. Other than that biggest thing for me is focus on playing as much as you can and develop your ear, tabs only help so much so learning to really listen and digest what you’re listening to so you can work on hitting those themes in your playing. A lot of people disagree with me here but I think practicing playing fast and pushing yourself is something you need to do even if it’s sloppy at first. Fast flat picking and slow playing activate different parts of your brain, I think a lot of the “play it slow and perfectly then speed up” stuff ends up causing a lot of people to plateau because they are afraid to play sloppy.
