“Your opinion of your mental capacity may be great, but if your idea of intelligence is crude, your intelligence-producing thought will also be crude, and can produce only crude intelligence. It is therefore evident that to simply think that you are brilliant will not produce brilliancy, unless your understanding of brilliancy is made larger, higher and finer. …. When your thinking is brilliant, you will be brilliant, but if your thinking is not brilliant you will not be brilliant, no matter how brilliant you may think you are.”
