Quote by Lewis Terman

"Intelligence is not a single general ability, but a collection of more or less independent abilities."

"The gifted individual is one who sees relationships among things."

"Genius is not born; it is made."

"The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
