“You can't control what you can't measure”

“You can't control how lucky you are, you can't control how smart you are, but you can control how hard you work.”

“You can't control everything. You can't control how someone feels about you. Or what makes them tick. You can only control how you react, how you act, how you think and feel.”

“You don't know what it's like to have something happening inside you, that you can't see and can't control, and know it's all slipping through your fingers.”

“You can't measure time the way you measure the distance between two points.”

“Your reputation is in the hands of others. That's what the reputation is. You can't control that. The only thing you can control is your character.”

“Government want to tell you things you can't say because they're against the law, or you can't say this because it's against a regulation, or here's something you can't say because its a… secret; "You can't tell him that because he's not cleared to know that." Government wants to control information and control language because that's the way you control thought, and basically that's the game they're in.”

“I can't stand just sitting here not doing anything. You can't solve a problem by remote control.”

“…. there is a difference between hearing and listening. You can't always help what you hear. But you can control what holds your interest, what you choose to dwell on.”

“Stop overthinking. You can't control everything, just let it be.”
