"Rich Dad Poor Dad" is a personal finance book written by Robert Kiyosaki. The book explores the author's upbringing and the contrasting financial advice he received from his two fathers - his biological father (poor dad) and his best friend's father (rich dad). Kiyosaki shares the lessons he learned from his rich dad about money management, investing, and building wealth. The book challenges conventional wisdom about money and provides insights into how to think and act like the rich to achieve financial success.
