Lessons in Voice, Piano, Clarinet, Saxophone, Composition and Oboe. Recorder and Flute by request. Classes in History and Theory.
Everyone worries that they don't practice enough. Sure it's important but without knowledge of what and how to practice it's pretty much useless or it can make you worse!.
I started teaching a recorder class when I was in grade 3, I have now been teaching for 45 years. I have not met one musician (other than folk/ pop ones who basically remain at a primitive level) who managed to figure it out for themselves without some guidance, there are just too many variables
This is what the "studies" say along with the 10,000 hour theory.
(lots of talented people never get good so you can't rely on this) You will have your strengths, weakness and tendencies, know and understand them.
These 2 are easy it's just a trip to the music store make sure you ask a pro first though as it's not a one size fits all kind of deal.
style, history, harmony, theory, practice tech, fingerings, psychology, fitness, physics.............
attitude, responsiveness, awareness of others, courage, consideration, discipline, trust, openness, resilience, patience, adaptability..........
Just for showing up.
So I can directly help you with 74% of your progress but only if you come to rehearsals and or lessons and I can help make sure that the last 26% is time well spent.
This is why in my adult band even players who rarely practice are improving.
