2 Book Summary: The Algebra of Happiness by Scott Galloway

Professor Scott Galloway distills his observations from teaching thousands of MBA students into a series of candid “equations” for a life of success, love, and meaning. This book is not a peer-reviewed study but a collection of no-nonsense advice from a serial entrepreneur, academic, and father.

2.1 The Arc of Life: Stress is Normal

Life follows a predictable U-shaped curve of happiness. Your youth is often magical, but your mid-twenties to mid-forties are typically marked by intense stress from building a career, starting a family, and confronting life’s harsh realities. Happiness tends to return in your fifties as you gain perspective, appreciate your blessings, and accept your mortality.

  1. Embrace the struggle: If you’re stressed in your 30s and 40s, recognise this is a normal part of the journey.
  2. Keep moving forward: Perspective and happiness are often waiting on the other side of this challenging period.

Galloway argues that if you prioritise balance in your twenties and thirties, you must accept you may not reach the upper echelons of economic security. The trajectory of your career is largely set in the first five years post-graduation. To make it steep, you need to burn a lot of fuel and work incredibly hard. Balance is a luxury earned through a prior lack of it.

2.2 The Most Important Decisions

  1. Your Life Partner: The most critical decision you’ll make is not your career, but who you choose as a life partner. A good partner magnifies the joys and softens the blows of life. Misalignment on core values with your spouse makes everything harder.
  2. Your Credentials & Location: In youth, focus on two things: getting credentialed (education) and getting to a city. Opportunity is a function of density. Big cities are competitive arenas that force you to improve your game. As Galloway puts it: Credentials + Zip Code = Money.
  3. Your Relationship with Sweat: “The ratio of time you spend sweating to watching others sweat is a forward-looking indicator of your success”. Prioritise physical activity and personal participation over passive consumption of entertainment.

Galloway’s advice is simple: Like someone who likes you. Young people often mistake rejection for a signal of a person’s high value. A person who genuinely thinks you’re great is a feature, not a bug. Beyond physical attraction, ensure you align on key values: religion, children, finances, and life goals. A partnership where 1+1 > 2 is built on this foundation.

2.3 Equations for a Well-Lived Life

  1. Invest Early and Often: Compound interest is the most powerful force in the universe, not just for money but for relationships. Small, consistent investments - texting friends, expressing admiration, telling people you love them - pay immense dividends over time.
  2. Experiences > Things: People consistently overestimate the happiness things will bring and underestimate the long-term positive effect of experiences. Drive a modest car and take incredible holidays.
  3. Equity = Wealth: It is difficult to achieve economic security on salary alone. As soon as possible, own assets that can appreciate, such as property or stocks. The definition of “rich” is having passive income greater than your burn rate.
  4. Resilience / Failure = Success: Everyone experiences failure and tragedy. The key to success is your ability to mourn, learn, and then move on. Your successes and failures are not entirely your fault; market dynamics often trump individual performance. Be less hard on yourself.

2.4 Other key ideas

This is one of Galloway’s most famous pieces of advice. People who tell you to “follow your passion” are usually already rich.

  1. Find what you’re good at.
  2. Put in the 10,000 hours to become great at it.
  3. The economic and emotional rewards that come from being great at something will make you passionate about it. Nobody starts out passionate about tax law, but a great tax lawyer becomes passionate about the respect, security, and opportunities their expertise provides.

A lack of basic professionalism can sabotage great talent. Galloway admits this has been a personal struggle. Focus on mastering the simple things:

  1. Show up early.
  2. Have good manners. Use “please” and “thank you.”
  3. Follow up. A timely response maintains momentum and shows respect. Not possessing these basic skills will hold you back from achieving your full potential.
  1. Give Someone a Good Death: Providing comfort and dignity to a loved one at the end of their life is a profound and deeply satisfying experience. If you have the opportunity to make a parent’s exit more graceful, do it. You will cherish it forever.
  2. Love a Kid Who Isn’t Your Own: In a world with high rates of divorce, caring for a child who isn’t biologically yours is one of the most noble forms of cooperation. It’s a direct path to making the world better and becoming more human.
  3. Be a Role Model: An adult taking an irrational interest in the well-being of a child who isn’t theirs can change that child’s life, making them feel visible and worthy.

4 Practise

Galloway stresses the importance of taking stock of what truly brings you joy. Use this exercise to apply his principles to your own life.

  1. Identify Your Joy: List 5-10 things that genuinely bring you joy, focusing on those that don’t involve a lot of money or substances (e.g., cooking, hiking, playing an instrument, spending time with a specific person).
  2. Track Your Time: For one week, roughly track how many hours you spend on the activities you listed vs. how much time you spend on passive entertainment (e.g., scrolling social media, watching TV).
  3. Make a Small Investment: Based on your findings, schedule just one extra hour in the upcoming week for one of the activities that brings you joy. This is a small, conscious investment in your own happiness, reflecting the principle of “compound interest.”
