Quote by Ludwig Wittgenstein

"Whereof one cannot speak, thereof one must be silent."

"The limits of my language mean the limits of my world."

"A picture held us captive. And we could not get outside it, for it lay in our language and language seemed to repeat it to us inexorably."

"The world is everything that is the case."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
