2 Book Summary: 100 Days Happier

“100 Days Happier” is built on a simple yet powerful premise: lasting happiness isn’t something you achieve once, but something you create every single day through conscious choices and actions. Dominique Bertolucci provides a daily guide to help you make small, consistent changes in your thinking and behaviour that lead to a fundamental shift in how you feel about yourself and your life. The core idea is to move away from waiting for happiness and start actively building it, one day at a time.

2.1 The Foundation: Happiness is a Daily Choice

The book’s central message is that you have the power to choose happiness. It’s not about waiting for external circumstances to be perfect, but about adopting a proactive mindset.

  1. Consciously Choose Happiness: Each morning, decide that you want to have a happy day. This simple intention sets the tone and directs your focus towards actions and thoughts that support your wellbeing.
  2. Focus on Today: While it’s good to learn from the past and dream of the future, true happiness is found in the present moment. Concentrate your energy and attention on making today the best it can be.
  3. Adopt the Right Attitude: Your expectations shape your experience. Start each day expecting good things to happen. A positive attitude helps you navigate challenges more effectively and appreciate the good, regardless of external events.

The author suggests not just reading the book cover-to-cover, but engaging with it daily. Each day, choose one page - either in sequence or at random - and commit to putting that single idea into action. This consistent practice is what turns these concepts into ingrained, happiness-boosting habits.

2.2 Taking Control: Proactivity and Personal Responsibility

A significant portion of the book focuses on moving from a passive to an active role in your own life. This involves taking ownership of your choices, actions, and reactions.

  1. Take Action, Don’t Worry: Worrying is a misuse of energy. If you face a problem, ask yourself if you can do something about it. If yes, take action. If no, accept it and move on.
  2. Make Conscious Decisions: Avoid drifting through life. Be decisive in your choices, both big and small. Taking charge of your decisions builds confidence and ensures your life is moving in a direction you have chosen.
  3. Stop Holding Yourself Back: Pay attention to your inner dialogue. Challenge self-limiting beliefs and the excuses you make. Ask yourself, “How do I hold myself back?” and then get out of your own way.

Bertolucci highlights several common traps that sabotage happiness. Be mindful of:

  • Perfectionism: Aiming for your best is healthy; aiming for perfection is an impossible goal that leads to stress and disappointment. Your best is always good enough.
  • Keeping Score: In relationships, generosity fosters connection. Keeping a tally of who did what last creates resentment. Be the first to act.
  • Self-Pity: When things go wrong, avoid the “Why me?” mindset. Instead of feeling sorry for yourself, focus on what you can learn or how things could be worse to gain perspective.

2.3 Other key ideas

Your relationship with yourself is the foundation for a happy life.

  1. Treat Yourself with Respect: Your inner dialogue matters. Speak to yourself with the same kindness, patience, and love you would offer a good friend.
  2. Give Yourself Permission: You deserve to be happy. Give yourself permission to pursue what you want, to rest when you need it, and to have a fulfilling life without making excuses.
  3. Guard Your Self-Esteem: Don’t rely on others for validation. Nurture your self-belief so that it becomes self-sustaining. Know that you are good enough, just as you are.
  4. Don’t Criticise Yourself: Instead of judging your successes and failures, evaluate your efforts. Focus on whether you gave yourself a fair chance, not on a flawless outcome.

The book encourages shifting from a “poverty mentality” to one of abundance, which has less to do with money and more to do with perspective.

  1. Count Your Blessings: Make time each day to acknowledge how fortunate you are. Gratitude shifts your focus from what’s missing to the richness already present in your life.
  2. Decide to Feel Rich: A “poverty” mentality focuses on lack. Even if you have goals you’re still working towards, recognise that you likely already have everything you truly need.
  3. Focus on What You Have: Every time you catch yourself thinking “I want…”, challenge yourself to replace it with “I have…” and acknowledge something that is already yours.

True happiness requires learning to release control over things you cannot change.

  1. Don’t Waste Energy: Many things in life are beyond your control. Identify what you can influence and peacefully accept the rest.
  2. Walk Away from Unwinnable Battles: Choose your battles wisely. If a situation or argument is not worth your energy, take a deep breath and walk away.
  3. Learn to Let Go: The need to control everything is exhausting and often stems from insecurity. Letting go saves energy and boosts self-esteem by trusting that things will be “good enough” even if they aren’t perfect.
  4. Look for the Lesson: When things don’t go as planned, shift your perspective from disappointment to learning. Ask, “What did I learn?” and “What would I do differently next time?” This turns every experience into a positive one.

4 Practise

The most effective way to practise the principles in this book is to integrate them into your daily routine. Create a “Daily Happiness Ritual”:

  1. Morning Intention (2 minutes): When you wake up, pick one idea from the book. You can read a random page or follow it sequentially. State the day’s principle as your intention (e.g., “Today, I will focus on doing one thing at a time”).
  2. Midday Check-in (1 minute): Pause for a moment in the afternoon. How is your intention going? Take three deep breaths and gently bring your focus back to your chosen principle.
  3. Evening Reflection (3 minutes): Before bed, reflect on your day. Acknowledge one thing you are grateful for and recognise the progress you made, no matter how small.
