The world takes us at our own valuation. It believes in the man who believes in himself, but it has little use for the timid man, the one who is never certain of himself; who cannot rely on his own judgment, who craves advice from others, and is afraid to go ahead on his own account. -from "The Rulers of Destiny" The preeminent self-help expert of the early 20th century and a forerunner of Dale Carnegie and Norman Vincent Peale, Stephen R. Covey and Anthony Robbins, Marden penned numerous motivation books that galvanized the public. In this insightful and motivating little book, first published in 1901 and just as enlightening today, he explores the importance of mental discipline to our happiness and success. Topics covered include: . training the will . "the wills, won'ts, and can'ts" . what is worse than rashness . conquerors of fortune . concentrated energy . persistent purpose . and more.
