“Hard work and training. There's no secret formula. I lift heavy, work hard and aim to be the best.”

Context: All leaders are human. They get tired, angry, and jealous and carry the same range of emotions and frailties common to mankind. Most leaders periodically display them. The leaders I most admired were totally human but constantly strove to be the best humans they could be. Leaders make mistakes, and they are often costly. The first reflex is normally to deny the failure to themselves; the second is to hide it from others, because most leaders covet a reputation for infallibility. But it's a fool's dream and inherently dishonest. There are few secrets to leadership. It is mostly just hard work. More than anything else it requires self-discipline. Colorful, charismatic characters often fascinate people, even soldiers. But over time, effectiveness is what counts. Those who lead most successfully do so while looking out for their followers' welfare.

Farewell speech at the Champs-Élysées podium, after winning his seventh Tour de France, quoted in "Paris salutes its American hero" by Caroline Wyatt in BBC News (24 July 2005) http://news.bbc.co.uk/2/low/europe/4713283.stm
Context: Finally, the last thing I’ll say to the people who don’t believe in cycling, the cynics and the sceptics: I'm sorry for you. I’m sorry that you can’t dream big. I'm sorry you don't believe in miracles. But this is one hell of a race. This is a great sporting event and you should stand around and believe it. You should believe in these athletes, and you should believe in these people. I'll be a fan of the Tour de France for as long as I live. And there are no secrets — this is a hard sporting event and hard work wins it. So Vive le Tour forever!

"College Education," an address before the Literary the Eclectic Institute (June 1867), in President Garfield and Education : Hiram College Memorial (1881) by B. A. Hinsdale, p. 312 http://books.google.com/books?id=rA4XAAAAYAAJ

1900s, A Square Deal (1903)
Context: Among ourselves we differ in many qualities of body, head, and heart; we are unequally developed, mentally as well as physically. But each of us has the right to ask that he shall be protected from wrong-doing as he does his work and carries his burden through life. No man needs sympathy because he has to work, because he has a burden to carry. Far and away the best prize that life offers is the chance to work hard at work worth doing; and this is a prize open to every man, for there can be no better worth doing than that done to keep in health and comfort and with reasonable advantages those immediately dependent upon the husband, the father, or the son. There is no room in our healthy American life for the mere idler, for the man or the woman whose object it is throughout life to shirk the duties which life ought to bring. Life can mean nothing worth meaning, unless its prime aim is the doing of duty, the achievement of results worth achieving.
