All of the great leaders down through history have told us we become what we think about. In fact, they have been in complete and unanimous agreement on this point while they disagree on almost every other point. Unfortunately, the vast majority of people rarely think, they simply accept what they see or hear. The next time someone gives you a suggestion, rather than simply accepting and acting on the suggestion - THINK - exercise your reasoning factor. Ask yourself if the suggestion will improve the quality of your life.
