Quote by Carl Sagan

"Somewhere, something incredible is waiting to be known."

"The cosmos is a vast living body, of which we are still parts."

"Science is a way of thinking much more than it is a body of knowledge."

"For small creatures such as we, the vastness is bearable only through love."

"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."
