“I can't think of anything that anyone has ever accomplished without having some sort of self-discipline. Without knowing how to work for it. Without learning how to earn it. I talk to my friends who are writers. I say, "Well, how do you do it?" Most all of them will say, "I sit down. I force myself every day to sit down and write for at least two hours. Whether something comes out of it or doesn't come out of it, whether I finish my fifty pages or two, I sit down and I do that because I have to make myself do it."

That's what a work ethic is. Any person I know who is successful in my business or any other business is so because they work their asses off for it, because nothing is for free. If you want something, if you want to achieve success in any area of life, you must apply your discipline and your work ethic. Because discipline is what helps you consciously do things in order to reach a desired goal. Discipline is a rejection of entitlement and expectation. Discipline is having a strong awareness that your choices have impact and that your actions make a difference.”

“You live in a world where you can drive through the drive-thru, flop down in a chair to work all day, and spend your evening on the couch, in front of the TV, before you crawl off to your cozy bed. Even if you work hard all day, your day-to-day living can make your body soft. And that softness is a modern-day killer, the equivalent of the savanna-dweller’s lion (actually, the lion was better, since it kept people moving).”
