Men speak of "building up a business," and, indeed, a business is as much a building as is a brick house or a stone church, albeit the process of building is a mental one. 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. Nothing could injure it; nothing could undermine its prosperity, nothing could interrupt its success, or bring it to the ground; but that success would be assured with incessant increase so long as the principles were adhered to.
