“The best way to weaken one's enemy was to get him to believe that you were on his side.”

“Don't explain. Your friends do not need it, and your enemies will not believe you”

“Only the following items should be considered to be grave faults: not respecting another's rights; allowing oneself to be paralyzed by fear; feeling guilty; believing that one does not deserve the good or ill that happens in one's life; being a coward. We will love our enemies, but not make alliances with them. They were placed in our path in order to test our sword, and we should, out of respect for them, struggle against them. We will choose our enemies.”

“The more attention you pay an enemy, the stronger you make him. Be attentive, but don't be paranoiac.”

“Things do not always happen the way I would have wanted, and it's best that I get used to that.”

“Some things are governed by common sense. Putting buttons on the front of a shirt is a matter of logic, since it would be very difficult to button them up at the side, and impossible if they were at the back. “Other things, however, become fixed because more and more people believe that’s the way they should be. I’ll give you two examples. Have you ever wondered why the keys on a typewriter are arranged in that particular order?”

“If everybody loves you, something is wrong. Find at least one enemy to keep you alert.”
