“Concentrate every minute like a Roman— like a man— on doing what’s in front of you with precise and genuine seriousness, tenderly, willingly, with justice. And on freeing yourself from all other distractions. Yes, you can— if you do everything as if it were the last thing you were doing in your life, and stop being aimless, stop letting your emotions override what your mind tells you, stop being hypocritical, self-centered , irritable. You see how few things you have to do to live a satisfying and reverent life? If you can manage this, that’s all even the gods can ask of you.”
― Marcus Aurelius, Meditations

“If anyone tells you that a certain person speaks ill of you, do not make excuses about what is said of you but answer, "He was ignorant of my other faults, else he would not have mentioned these alone.”
― Epictetus

“Don't ever let someone tell you, you can't do something. Not even me. You got a dream, you got to protect it. People can’t do something themselves, they want to tell you you can’t do it. You want something, go get it. Period.”
― Pursuit of Happyness

“Our life is frittered away by detail...Simplicity, simplicity, simplicity! I say, let our affairs be as two or three, and not a hundred or a thousand...Simplify, simplify!”
― Henry David Thoreau, Walden or, Life in the Woods
