As A Man Thinketh (1902), Visions and Ideals
Source: As a Man Thinketh
Context: To desire is to obtain; to aspire is to, achieve. Shall man's basest desires receive the fullest measure of gratification, and his purest aspirations starve for lack of sustenance? Such is not the Law: such a condition of things can never obtain: "ask and receive."
Dream lofty dreams, and as you dream, so shall you become. Your Vision is the promise of what you shall one day be; your Ideal is the prophecy of what you shall at last unveil.

The Cunning Man (1994)
Context: The ironist is not bitter, he does not seek to undercut everything that seems worthy or serious, he scorns the cheap scoring-off of the wisecracker. He stands, so to speak, somewhat at one side, observes and speaks with a moderation which is occasionally embellished with a flash of controlled exaggeration. He speaks from a certain depth, and thus he is not of the same nature as the wit, who so often speaks from the tongue and no deeper. The wit's desire is to be funny; the ironist is only funny as a secondary achievement.

Variant: Desire is the starting point of all achievement, not a hope, not a wish, but a keen pulsating desire which transcends everything.
As quoted in Quote-A-Quote: To Your Success Health Wealth & Happiness (2005) by Michael E. Ruge, p. 38
Context: Strong, deeply rooted desire is the starting point of all achievement. Just as the electron is the last unit of matter discernible to the scientist. DESIRE is the seed of all achievement; the starting place, back of which there is nothing, or at least there is nothing of which we have any knowledge.
