This is really a trick. Lately It's difficult to find a song I like. Most of them became boring or let's say not motivating to learn them.

I am really puzzled about what to learn next and I do not know where to get a good advice that is "workable" in my current situation.

I play by ear and can figure out chords for compositions I like and if I can't I may search the internet for the hard parts but usually I am too lazy to do it and it's more interesting to figure it out by myself. Also because lately I see that internet versions are frequently "worse" or even wrong or too primitive ignoring all they beauty of complicated chords.

So I am pleased with what I have on the one hand. On the other hand I am stuck with question what to learn next? I never master pieces to the complete perfection because honestly I do not perform for the public and so I find it hard to motivate myself with that because who needs another moderate piano player these days when there are plenty of trained pianists available? How many chances I have to win competition with "well trained" people? And who would wish to listen unless you are "perfect"? So what is the point? I play for myself or my friends but if I wish some piece to sound better I find it difficult to achieve even though I know that I am more than capable to improve them to a much better level. So I can't reasonably motivate myself as a "performer/future performer" to sit and train for many hours. I've heard that this "many hours training" could also rise my level of understanding theory but I do not see a direct connection between those.

Perhaps I just do not see it and thus do not know how to progress and choose what to learn next to move forward? Any advice?
