I'm looking for an exact quote of Ren's. I forgot exactly when he says it and to whom he says it, but I do remember that's fairly early on and, I think, to either Nana, Yasu, or possibly Nobu.
Anyway, the essence of the quote is this: "It doesn't matter if you're born with talent; if you play that much, you're bound to get good."
Any help that you could give me would be great. :)
