The document discusses the importance of attitudes and how they impact behavior. It defines attitudes as a mental position regarding facts or states that influence how objects and events are classified and reacted to consistently. Attitudes are inferred from responses rather than directly observed. Several studies highlighted in the document show that attitudes were a stronger determinant of success, customer retention, and job performance than other factors like skills, education, or appearance. The document advocates focusing on changing behaviors, as behaviors shape attitudes over time, rather than directly trying to change underlying attitudes which can be difficult to control. Repeatedly choosing new behaviors in different situations can help reshape attitudes in a positive direction.
