thinks wholly into the future. He is extroverted toward his environment. He clearly observes the environment with full perception unclouded by undistinguished fears about the environment. He thinks very little about himself but operates automatically in his own interests. He enjoys existence. His calculations (postulations and evaluations) are swift and accurate. He is very self-confident. He knows he knows and does not even bother to assert that he knows. He controls his environment.
