Sách nói: Eight Pillars of Prosperity (Version 2)

“Prosperity, like a house, is a roof over a man’s head, affording him protection and comfort. A roof presupposes a support, and a support necessitates a foundation. The roof of prosperity, then, is supported by the following eight pillars which are cemented in a foundation of moral consistency:
1. Energy
2. Economy
3. Integrity
4. System
5. Sympathy
6. Sincerity
7. Impartiality
8. Self-reliance
A business built up on the faultless practice of all these principles would be so firm and enduring as to be invincible.” - Summary by James Allen
