Strong, deeply rooted desire is the starting point of all achievement. Just as the electron is the last unit of matter discernable 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.
A definite chief aim, which is only another name for DESIRE, would be meaningless unless based upon a deeply seated, strong desire for the object of the chief aim. Many people “wish” for many things, but a wish is not the equivalent of a strong DESIRE, and therefore wishes are of little or no value unless they are crystallized into the more definite form of DESIRE.
~ Napoleon Hill, The Law of Success (1928)
