"Rich Dad Poor Dad" by Robert Kiyosaki is a personal finance book that contrasts the financial philosophies of two father figures: his own educated but financially struggling "Poor Dad," and his friend's wealthy and financially savvy "Rich Dad." The book emphasizes the importance of financial education, investing, building assets, and developing an entrepreneurial mindset. Key lessons include understanding the difference between assets and liabilities, making money work for you, and thinking differently about money than the traditional 9-to-5 mindset.
