"If there is no enemy within, the enemy outside can do us no harm."
- African proverb
"Here's to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They're not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do is ignore them. Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do."
- Apple, Think Different
"We are what we repeatedly do. Excellence then is not an act, but a habit."

"I don’t know the key to success, but the key to failure is trying to please everyone."
- Bill Cosby
"A human being is a part of the whole called by us "Universe", a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest—a kind of optical delusion of his consciousness. The striving to free oneself from this delusion is the one issue of true religion. Not to nourish the delusion but to try to overcome it is the way to reach the attainable measure of peace of mind."
- Albert Einstein, Ideas and Opinions
"On the piano, play mainly the things that you enjoy, even if your teacher doesn't assign them to you. You learn the most from things you enjoy doing so much that you don't even notice that the time is passing. Often I'm so engrossed in my work that I forget to eat lunch."
- Albert Einstein, Letter to Hans Albert (1915)
"You can tell more about a person by what they say about others than you can by what others say about them."
- Audrey Hepburn
"That's been one of my many mantras—focus and simplicity. Simple can be harder than complex: you have to work hard to get your thinking clean to make it simple. But it's worth it in the end because, once you get there, you can move mountains."
- Steve Jobs
"When you grow up, you tend to get told the world is the way it is and your life is just to live your life inside the world... That’s a very limited life. Life can be much broader once you discover one simple fact, and that is - everything around you that you call life, was made up by people that were no smarter than you. And you can change it, you can influence it, you can build your own things that other people can use... That’s maybe the most important thing. It’s to shake off this erroneous notion that life is there and you’re just gonna live in it versus embrace it, change it, improve it, make your mark upon it... Once you learn that, you’ll never be the same again."
- Steve Jobs, Secrets of Life Interview (1994)
"I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."
- Michael Jordan
"The most beautiful people we have known are those who have known defeat, known suffering, known struggle, known loss, and have found their way out of the depths. These persons have an appreciation, a sensitivity, and an understanding of life that fills them with compassion, gentleness, and a deep loving concern. Beautiful people do not just happen."
- Elisabeth Kubler-Ross, Death: The Final Stage of Growth
"Everyone you will ever meet knows something you don't."
- Bill Nye
"It is our failure to become our perceived ideal that ultimately defines us and makes us unique. It's not easy, but if you accept your misfortune and handle it right your perceived failure can become a catalyst for profound re-invention."
- Conan O'Brien, Dartmouth's Commencement Speech (2011)
"What we face may look insurmountable. But I learned something from all those years of training and competing. I learned something from all those sets and reps when I didn't think I could lift another ounce of weight. What I learned is that we are always stronger than we know."
- Arnold Schwarzenegger
"A man with a watch knows what time it is. A man with two watches is never quite sure."
- Segal's Law
