“We don't know what we don't know.”
“What we know is a drop, what we don't know is an ocean.”
“What we know is not much. What we don't know is enormous.”
“Sometimes we don't know what we want until we don't get it.”
“We don't know in advance what we're going to do in the future, but the truth is we often don't know what we were thinking in the past.”
“...none of us knows anything. We think we know, then it turns out that we don't. The universe has a way of intervening. Of changing you. In the end, you don't know what you're seeking, and you don't know what you'll find.”
