The Algebra of Wealth: A Simple Formula for Financial Security is a book by Scott Galloway, a professor at NYU Stern School of Business. The book argues that the traditional advice of "work hard, save money, and invest wisely" is no longer enough to achieve financial security in today's economy. Instead, Galloway proposes a new formula for wealth creation that includes focus, stoicism, time, and diversification.

• Focus means developing a specific and valuable skill set. Galloway argues that people who are good at many things are rarely great at anything, and that greatness is what leads to wealth.
• Stoicism is the practice of delayed gratification and living below your means. Galloway argues that people who are able to save money and avoid lifestyle inflation are more likely to achieve financial security.
• Time is one of the most important factors in wealth creation. Galloway argues that starting to save and invest early is essential for building wealth over time. The power of compound interest can significantly grow your wealth over time.
• Diversification is the practice of investing in a variety of assets to reduce risk. Galloway argues that diversification is essential for protecting your wealth from unexpected events.

The Algebra of Wealth has been praised for its clear and concise writing style, as well as its practical advice. Galloway's focus on focus, stoicism, time, and diversification is a valuable framework for anyone who wants to achieve financial security.
