“A brave man is one who admits his fear. Only a fool believes himself invincible.”

“A man who does not fool himself seldom cares much about fooling others. But the man who claims to have seen a ghost wants everybody else to believe in ghosts.”

“I believe that the only protection that man has against himself is the trust and confidence of his friends. For example, my cynicism tells me that the man who makes a career of "people-hunting" or "people-hating" is a man who desperately fears being chased or not loved.”

“To believe yourself brave is to be brave; it is the one only essential thing.”

“The Brave man is not he who does not feel afraid, but he who conquers that fear”

“Any man who does not make himself proficient in at least two languages other than his own is a fool”

“The brave man is not he who feels no fear,
For that were stupid and irrational;
But he, whose noble soul its fear subdues,
And bravely dares the danger nature shrinks from.”

“A man who says he feels no fear is either a fool or a liar.”

“Only a man who is at one with the world can be at one with himself.”

“Nor is he the wisest man who never proved himself a fool.”
