I've been thinking that probably most of these giants in his-story are just made up like Mozart, to dumb us down, to make it seem impossible for us ordinary folks to match the level of these masters who were natural born talent... all bs I bet.
Bach is probably not responsible for all his works. The concerto for 4 harpsichords sounds a lot like a Vivaldi song, ect...
And 777 pretty much proved Divine Chi was also a made up character, even if just by his name alone.
And Shakespeare, how much controversy brews over his authenticity? Quite a lot that's for sure.
We all have the ability to be any of these characters, all we need to do is try, and try again.
