In Give and Take, Adam Grant challenges the traditional notion that success is achieved primarily through self-interest and competition. Instead, he argues that people who adopt a giving approach—helping others without expecting anything in return—are often the most successful and fulfilled in life and work. Drawing on research from psychology, economics, and social science, Grant identifies three types of people: givers, takers, and matchers.

• Givers are those who contribute to others without expecting anything in return.
• Takers tend to look out for themselves, trying to get as much as they can.
• Matchers aim for a balance of give and take, often reciprocating favors but not necessarily going out of their way to help others.
