Knowledge becomes power only when...

And that is another reason why it pays to start one or two steps above the bottom. By so doing one forms the HABIT of looking around, of observing how others get ahead, of seeing OPPORTUNITY, and of embracing it without hesitation.

Most of the professors have but little or no money. They specialize on teaching knowledge, but they do not specialize on the organization, or the use of knowledge.
KNOWLEDGE will not attract money, unless it is organized, and intelligently directed, through practical PLANS OF ACTION, to the DEFINITE END of accumulation of money. Lack of understanding of this fact has been the source of confusion to millions of people who falsely believe that "knowledge is power." It is nothing of the sort! Knowledge is only potential power. It becomes power only when, and if, it is organized into definite plans of action, and directed to a definite end.
