“My formula for happiness: a Yes, a No, a straight line, a goal.”

“My goal is to draw a line with some 'flavor' to it.”

“The sacred formula of positivism: love as a principle, the order as a foundation, and progress as a goal.”

“More important than success is the individual who strives towards his goal. It is the effort which counts. The goal is just a finish line - it accomplishes there and its happiness short lived.”

“And therein lies the whole of man's plight. Human time does not turn in a circle; it runs ahead in a straight line. That is why man cannot be happy: happiness is the longing for repetition.”

“This is tantamount to saying, "My hand is weak. I cannot draw a straight line,—that is, a line which will be the shortest line between two given points,—and so, in order to make it more easy for myself, I, intending to draw a straight, will choose for my model a crooked line." The weaker my hand, the greater the need that my model should be perfect.”
