The following is a personality profile of Dale Carnegie based on his work.
Dale Carnegie is boisterous, unpretentious and can be perceived as dependent.
He is assertive, he tends to speak up and take charge of situations, and he is comfortable leading groups. He is intermittent as well: he has a hard time sticking with difficult tasks for a long period of time. But, Dale Carnegie is also empathetic: he feels what others feel and is compassionate towards them.
More than most people, his choices are driven by a desire for discovery.
Considers helping others to guide a large part of what he does: he thinks it is important to take care of the people around him. He is also relatively unconcerned with achieving success: he makes decisions with little regard for how they show off his talents.
