The intelligence is closer to humility, as Jung said: Nature is aristocratic: always prevails and is dominion over the human aspirations. A smart way is one that having been informed about the mental processes, respects and leverages its dynamics to generate profits. No battle against them. Working in the mind of a productive way is just use the natural process of human mind but in a way that is productive and generate the optimal emotional state that can respond to life as we want. The way that you think reflects the tidal energy which you are planted today, and thus leads to negative thoughts and feelings that seized adverse. It is the magnetism of the emotional tide where you are what attracts them. For this reason, efforts to control them, setting them aside, numb, sleep, postponed, deny them and replace them will become more intense and less productive.
Their views are equally limited. To the extent that you stay in those seas of turbid water, the result will be the same mental journey will always be similar, limited, get the same mental scenarios that will produce those charged emotional climate you already know. The good news is that these problems can be reversed just as plain and unnoticeable and can start because the same mental processes are valid for positive states as well: they also attract a multitude of ideas, circumstances, people, subjects, objects of equivalent energy, ie attract overseas profits and increased welfare. His thoughts and emotions define the tidal energy in which you are located.
