When will man learn that he is the cause of his own feelings for either happiness or anxiety?”

“Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth.”

“When life hands you a lemon, say "Oh yeah, I like lemons. What else you got?”

“Anxiety is love's greatest killer. It creates the failures. It makes others feel as you might when a drowning man holds on to you. You want to save him, but you know he will strangle you with his panic.”

“Man tells his aspiration in his God; but in his demon he shows his depth of experience; and casts light into the cavern through which he worked his cause up to the cheerful day.”
