Gordon Allport Quote

We cannot know the young child's personality by studying his systems of interest, for his attention is as yet too labile, his reactions impulsive, and interests unformed. From adolescence onward, however, the surest clue to personality is the hierarchy of interests, including the loves and loyalties of adult life.
