"Functions are concepts; concepts are functions."

"The content of a thought may have different kinds of parts."

"I'm not angry, I'm just disappointed."

"The best things in life are free."

"You can't have everything in life, but you can have what matters most."

"A woman's intuition is rarely wrong."
