"Life is what happens when you're busy making other plans."

"In the end, it's not the years in your life that count. It's the life in your years."

"We suffer more often in imagination than in reality."

"You have power over your mind - not outside events. Realize this, and you will find strength."

"The unexamined life is not worth living."

"To live is the rarest thing in the world. Most people exist, that is all."

"Turn your wounds into wisdom."

"Life is 10% what happens to you and 90% how you react to it."
