>Napoleon Hill, Think and Grow Rich, Chapter 11 "The Mystery of Sex Transmutation"
Sex desire is the most powerful of human desires.
When driven by this desire, men develop keenness of imagination, courage, will-power, persistence, and creative ability unknown to them at other times. So strong and impelling is the desire for sexual contact that men freely run the risk of life and reputation to indulge it. When harnessed, and redirected along other lines, this motivating force maintains all of its attributes of keenness of imagination, courage, etc., which may be used as powerful creative forces in literature, art, or in any other profession or calling, including, of course, the accumulation of riches.
The transmutation of sex energy calls for the exercise of will-power, to be sure, but the reward is worth the effort. The desire for sexual expression is inborn and natural. The desire cannot, and should not be submerged or eliminated. But it should be given an outlet through forms of expression which enrich the body, mind, and spirit of man. If not given this form of outlet, through transmutation, it will seek outlets through purely physical channels.
A river may be dammed, and its water controlled for a time, but eventually, it will force an outlet. The same is true of the emotion of sex. It may be submerged and controlled for a time, but its very nature causes it to be ever seeking means of expression. If it is not transmuted into some creative effort it will find a less worthy outlet.
Fortunate, indeed, is the person who has discovered how to give sex emotion an outlet through some form of creative effort, for he has, by that discovery, lifted himself to the status of a genius.
