Never discriminate as to whom you study and whom you trust. Never trust anyone completely and study everyone, including friends and loved ones.

In general, the best thing to do when you suspect people of trying to distract you from the truth is not to actively confront them in the beginning, but in fact to encourage them to continue by showing interest in what they are saying or doing. You want them to talk more, to reveal more signs of tension and contrivance. At the right moment you must surprise them with a question or remark that is designed to make them uncomfortable, revealing you are onto them. Pay attention to the microexpressions and body language they emit at such moments. If they are really deceiving, they will often have a freeze response as they take this in, and then quickly try to mask the underlying anxiety. This was the favorite strategy of detective Columbo in the television series of the same name—facing criminals who had tried to reverse engineer the evidence to make it look like someone else had done it, Columbo would pretend to be perfectly friendly and harmless but then would suddenly ask an uncomfortable question and then pay extra attention to the face and body.

In the end, the money and success that truly last come not to those who focus on such things as goals, but rather to those who focus on mastery and fulfilling their Life’s Task.
