True, YT bristles with phenomenal pianists, many of them you've never even heard of. But there
are just as many bad pianists around. It is quite inconceivable that one would be a worse pianist than all of these ;-)
I like to cheer myself up sometimes with this original thought : Ok, so there's 100000 pianists who play so much better than I do. So what ! There are countless of millions who play much worse, or not at all, and would look up at me in awe for playing even a simple piece. I'm still
one of the, what, 1% of people who can play halfway decently at all.
Hope that helps ! And as said, it is not about who is better than who anyway. As long as you
are still improving your own playing, there's nothing to worry about.
