Euclid

“Have confidence in yourself and don't let people put you down or make you feel weak or worthless, because the more they put you down, the more you need to get back up and prove how wrong they are.”
“Empathy isnâ€™t just listening, itâ€™s asking the questions whose answers need to be listened to. Empathy requires inquiry as much as imagination. Empathy requires knowing you know nothing. Empathy means acknowledging a horizon of context that extends perpetually beyond what you can see.”
“What we call evil doesn't necessarily deserve any kind of respect or understanding, by any means; it just deserves an acknowledgement of its complexity so we can better understand it - so we can help prevent it.”
“Life is too full of distractions nowadays. When I was a kid we had a little Emerson radio and that was it. We were more dedicated. We didn't have a choice.”
“I always adored Cary Grant. I was fascinated by him. But I could never get too close to him.”
“Even today, I dare not say that I have reached a state of achievement. I'm still learning, for learning is boundless.”
“Fear doesn't exist anywhere except in the mind.”
“We are made of stardust; why not take a few moments to look up at the family album?”
