In As a Man Thinketh, James Allen showed how our thoughts and dreams determine the sort of person we become. In Eight Pillars of Prosperity, he reveals—in great depth and detail—the exact qualities we must meditate upon in order to achieve lasting success. Prosperity rests on eight pillars: Energy, Economy, Integrity, System, Sympathy, Sincerity, Impartiality, and Self-reliance. "A business built up on the faultless practice of all these principles," Allen writes, "would be so firm and enduring as to be invincible. Nothing could injure it; nothing could undermine its prosperity, nothing could interrupt its success."
