Part four: how to love, how to work. Professor brian little is a former harvard university psychology professor who won the 3m. Teaching fellowship: he is a very entertaining and enthusiastic lecturer and his lectures are often over-booked. But at the same time, he enjoys living a quiet life in a secluded area: he prefers one-on-one conversations, reading, writing, and keeping to himself. Professor little describes himself as an introvert who makes himself appear as an extrovert when he is lecturing to his students. He goes by the theory of situationism. Situationism goes by the fact that our generalizations about people are misleading - there is no core self, only the various selves in different situations. An anecdote is told in which professor brian little did a lecture at the royal military college saint- Professor little created the free trait theory to describe how he acts. He believes that fixed traits and free traits can coexist.
