Quote by Leon Trotsky

"Life is not an empty abstraction in which man is free to move about in any direction he pleases."

"The permanent revolution, so to speak, is the derivative of the law of uneven and combined development of mankind."

"Defeatism is the enemy of the revolution."

"Without a revolutionary theory there can be no revolutionary movement."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
