Yeah, and if we ever fallin' off
I swear I'll remind you that
We're not who they are

from Drake (Ft. Chris Brown) – Yamaha Mama Lyrics on Rap Genius

He’s saying that feedback is important and that he finds motivation to do better when he hears negative comments. He also mentioned this in his track Headlines where he says “I had someone tell me I fell off, oooh I needed that."
He also knows the consequences of falling when he fell on stage during a New Jersey performance in 2009 and had to get knee surgery.
