Being guided by a teacher was invaluable and I recommend it to everyone. Mine focused on improvisation and music theory and i realy loved it. I was moving forward much faster than on my own. Unfortunately I lost trust in my teacher, after finding a little song on his youtube channel (he has a channel on which he teaches stuff with synthesia videos) that he shared a week after my first session with him, which resembled very much what I had been working on at home and shown him. I was really bummed out, never had the guts to ask him how that happened and stopped returning, because he kept asking me to play stuff that I worked on at home...and eventually I stopped playing alltogether.
After reading this article I got excited again about piano playing. Just found this awesome channel with lots of high quality synthesia teaching videos, including one of my favorite songs (Ab Ovo by Joep Beving: https://www.youtube.com/watch?v=3qRV68k3-jo )
