I've been playing piano/keyboard on and off for about 15 years. Done closing acts for huge recitals, played for churches, school plays, romantic interests
I was really forced to do it early on which was completely frustrating. I barely practiced and would often have to repeat the same lesson multiple times. There's really so much out there now, I believe you can definitely teach yourself. Through our lessons we really just used Alfred's Piano Course Books, and looking back I think I could have gotten to where I am now by myself especially with those books because they pretty much lay it out for you. The problem was personal development lol. I had no desire to do it, didn't focus on the end goal, didn't know how to break down big problems into smaller ones, no time management skills to be able to set aside some time to practice etc....this led to me quitting for years, coming back, hiring different teachers, being frustrated and practically dragged to lessons, parents wasting a lot of money...etc. I absolutely love it now though. I spend hours a day just listening to stuff I create. I guess what I'm trying to say is if u know the success process it really doesn't matter what you want to do. You can achieve it.
