" The most successful men and women on earth have had to correct certain weak spots in their personalities before they began to succeed. The most outstanding of these weaknesses which stand between men and women and success are INTOLERANCE, CUPIDITY, GREED, JEALOUSY, SUSPICION, REVENGE, EGOTISM, CONCEIT, THE TENDENCY TO REAP WHERE THEY HAVE NOT SOWN, and the HABIT OF SPENDING MORE THAN THEY EARN. "
