Oh man, i relate to you on dropping that title, but on piano in my case (an irony, knowing that Mishi plays it), i've stopped playing my keyboard (in fact, someone else borrowed to play it, although i was reluctant to give it), i've stopped watching piano tutorials, i just stopped because i didn't feel like playing, even though i was pretty good, my skills have now basically reset, i can only use my right hand now, unlike before where i could use both to play complicated songs, i think it's because i simply don't enjoy it anymore, perhaps in the future i'll pick up again.
