Behavior scientists say that each of us is either internally or externally focused. If you are internally focused, it means your behavior is governed by what is happening inside you. If you are externally focused, it means your behavior is determined by what is happening around you.
It is obvious that externally focused people are not as happy as internally focused folk. They are perpetually reacting to events going on around them. Consequently they feel out of control.
Behavioral scientists say that most of us are 70% one-way and 30% the other. Either the external or the internal dominates in our life. They also say we can choose to shift the locus of control in our lives. Each of us would do well to be less externally focused and more internally focused.
