“Knowledge is the antidote to fear”

“The minute you learn to love yourself, you won't want to be anyone else”

“Your mind must be stronger than your feelings”

“First they ignore you, then they laugh at you, then they fight you, then you win.”

“You have power over your mind—not outside events. Realize this, and you will find strength ”

“The one unchangeable certainty is that nothing is certain or unchangeable”

“If you're not stubborn, you'll give up on experiments too soon.”
