You have to know how other people think before you craft the right kind of response. - Robert Greene

You like to imagine yourself in control of your fate, consciously planning the course of your life as best you can. But you are largely unaware of how deeply your emotions dominate you. They make you veer toward ideas that soothe your ego. They make you look for evidence that confirms what you already want to believe. They make you see what you want to see, depending on your mood, and this disconnect from reality is the source of the bad decisions and negative patterns that haunt your life. Rationality is the ability to counteract these emotional effects, to think instead of react, to open your mind to what is really happening, as opposed to what you are feeling. It does not come naturally; it is a power we must cultivate, but in doing so we realize our greatest potential.

The key then to attaining this higher level of intelligence is to make our years of study qualitatively rich. We don't simply absorb information - we internalize it and make it our own by finding some way to put this knowledge to practical use.

People around you, constantly under the pull of their emotions, change their ideas by the day or by the hour, depending on their mood.

You must never assume that what people say or do in a particular moment is a statement of their permanent desires.
