“To succeed in the world we do everything we can to appear successful already.”

Source: Success! (1977), p. 284; a portion of this — "In order to succeed we must first believe that we can" — has become widely attributed to Nikos Kazantzakis on the internet, but without citation of any sources.
Context: The American system demands success, and in order to succeed we must first believe that we can. Yet our society, with its intolerance of failure and poverty, traps millions of people in positions where any kind of success seems impossible to contemplate, and in which failure itself is a kind of passive rebellion against their own misery and the social system which created it in the first place.
To succeed it is necessary to accept the world as it is and rise above it.

1860s, Second State of the Union address (1862)
Context: I do not forget the gravity which should characterize a paper addressed to the Congress of the nation by the Chief Magistrate of the nation, nor do I forget that some of you are my seniors, nor that many of you have more experience than I in the conduct of public affairs. Yet I trust that in view of the great responsibility resting upon me you will perceive no want of respect to yourselves in any undue earnestness I may seem to display. Is it doubted, then, that the plan I propose, if adopted, would shorten the war, and thus lessen its expenditure of money and of blood? Is it doubted that it would restore the national authority and national prosperity and perpetuate both indefinitely? Is it doubted that we here — Congress and Executive can secure its adoption? Will not the good people respond to a united and earnest appeal from us? Can we, can they, by any other means so certainly or so speedily assure these vital objects? We can succeed only by concert. It is not "Can any of us imagine better?" but "Can we all do better?" Object whatsoever is possible, still the question recurs, "Can we do better?"

As quoted in The Subconscious Diet : It's Not What You Put in Your Mouth; It Is What You Put in Your Mind (2005) by Hugh B. Sanders, p. 104 <!-- also quoted in The First Step : A Peek at the Real World (2006) by Gudmundur O. Sigurdarson, p. 41 -->
Context: Success means doing the best we can with what we have. Success is the doing, not the getting — in the trying, not the triumph. Success is a personal standard — reaching for the highest that is in us — becoming all that we can be. If we do our best, we are a success. Success is the maximum utilization of the ability that you have.
