2015, Remarks to the Kenyan People (July 2015)
Context: Every country and every culture has traditions that are unique and help make that country what it is. But just because something is a part of your past doesn’t make it right. It doesn’t mean that it defines your future. [... ] Just because something is a tradition doesn’t make it right.

Song lyrics

Variant: I feel the universe is telling me something. And it doesn't even matter if it's true or not. What matters is that I feel it, and believe it.
