The book talks about the roles that people play in different situations and explains why the Anti-hero role is best for self-growth. The hero role creates unnecessary stress by having unreasonably high standards while the Anti-hero finds the best solutions for issues which matters most, solving them at the root of the problem. It also helps people explore interpersonal relationships and helps people understand why people have irrational behaviours. Understanding relationships and behaviours can help improve both professional and personal relationships.
