Have you ever wondered why some people can feel happy and content even with ordinary life circumstances, while others, despite abundant resources, often feel anxious, empty, or even distressed? In fact, psychology has long told us that the “sources” of happiness are not as simple as we might imagine.
According to positive psychology research, our sense of happiness is roughly composed of three parts:
- 50% is determined by genetics: this is our “inborn happiness baseline,” which is relatively hard to change;
- 10% comes from life circumstances: such as income, job, marriage, living conditions, etc.;
- 40% is determined by our behaviors and thinking habits — and this 40% is exactly the source of happiness we have the most power to shape.
This 40% is not an insignificant fraction; it contains the core potential for our subjective well-being. In other words, happiness is not entirely dependent on luck or external conditions — more importantly, we can “learn” to be happy.
This series will guide you through 12 practical happiness actions summarized by positive psychologists, each backed by scientific experiments and practice, capable of effectively raising your happiness level and helping you generate more positive energy, inner strength, and emotional resilience in daily life.
In this first part, we will deeply explore the first two happiness actions: expressing gratitude and cultivating an optimistic mindset. Though seemingly simple, these practices can quietly change your perspective on life and even alter your life trajectory.
Happiness Action 1: Awaken the Power of Gratitude Within
Why is gratitude the switch to happiness?
When your heart is full of gratitude, your attention shifts away from scarcity, complaints, and anxiety toward focus on what you have, contentment, and hope. As psychologist Robert Emmons says: “Gratitude is a naturally arising feeling of wonder, thankfulness, and appreciation in life.”
Gratitude is not a superficial courtesy; it is a profound cognitive shift that teaches you to discover grace in the small details of life, even in adversity, to see shining hope.
The scientific benefits of gratitude
Multiple studies show that people who regularly feel grateful, compared to others:
- Experience less anxiety, depression, and loneliness;
- Are more likely to develop positive interpersonal relationships;
- Have stronger motivation, a clearer sense of purpose, and more stable mental states;
- Possess stronger immunity and better physical recovery.
Interestingly, gratitude is not just a result — it is itself a psychological skill that can be exercised and strengthened like a muscle through daily practice.
Practice 1: Write a “Gratitude Letter”

Choose someone you have long felt grateful toward but have never expressed it to — perhaps a childhood teacher, a friend, or even a stranger who once encouraged you. Write a letter describing how he or she helped you, what you gained from that experience, and what you still remember today.
Advanced version: Summon courage and read the letter aloud to the person or express it face-to-face. This greatly enhances emotional connection and significantly boosts your happiness level.
Practice 2: Keep a “Gratitude Journal”
Write down 3–5 things you are grateful for every day or week — they don’t have to be grand: “The sunshine was nice today,” “Lunch was delicious,” “A friend sent a warm message.” A gratitude journal is not a mere log but a way to re-examine the little overlooked blessings in life.
You can also try different gratitude themes, such as:
- Gratitude for your body — even just for smooth breathing;
- Gratitude for family — despite occasional disputes, you still support each other;
- Gratitude for failure — because it taught you growth.
Research shows that people who write gratitude journals once a week experience more lasting happiness after six weeks than those who write daily — the key is consistency and freshness.
Practice 3: Express Gratitude Creatively
Besides writing, you can express gratitude through drawing, photography, collage, handmade cards, etc. Perhaps send a “gratitude postcard” to a friend each week or create a “gratitude album” for yourself.
You will be surprised to find that when you actively express gratitude, people around you also receive positive influence, creating a quiet “virtuous cycle.”
Happiness Action 2: Illuminate Your Optimistic Mindset
What is optimism? It’s not blind positivity
Optimism is not forcibly ignoring problems or denying pain but rather a more positive explanatory style.
When facing setbacks, optimistic people see them as temporary, specific, and changeable; pessimistic people tend to attribute failure to themselves and see it as permanent and uncontrollable.
Psychologist Martin Seligman’s theory of “learned optimism” points out that we can train ourselves to change our explanatory style, thereby improving resilience and happiness.
Practice 1: Write Your “Best Possible Self”
Choose a quiet moment, and seriously write a journal entry:

“Suppose from today on, all your efforts succeed, and you become your ideal self. Describe your life one year, five years, and ten years from now. What goals have you achieved? What meaningful work are you doing? Who are the people around you? What is your daily life like?”
This exercise not only activates positive imagination about the future but helps clarify your true values and life direction. Regular writing strengthens your sense of hope and purpose.
Practice 2: Cognitive Restructuring
Our brains are naturally biased toward negative information, known as the “negativity bias.” But we can consciously train ourselves to see things from another perspective.
For example:
- Change “I was unlucky and late today” to “Although I was late, I learned to leave 10 minutes earlier next time”;
- Change “This person is difficult” to “Maybe he is going through some hardship I don’t know about.”
This way of viewing the world determines whether you live in shadow or sunlight every day.
Practice 3: “Three Good Things” Exercise
Before going to sleep each night, write down three good things that happened that day and why they happened. This helps gradually and steadily improve your positive evaluation of life.
Examples:
- “A friend sent a caring message — because I usually care about others”;
- “I felt good today — because I had a healthy breakfast after morning jogging”;
- “Finished my task on time — because I didn’t watch shows at noon and focused on work.”
After 21 days, you will see noticeable improvement in your psychological state.
You Hold the Initiative of Happiness
If you often feel anxious, depressed, or lack purpose, try starting with one of these two happiness actions immediately. Don’t rush for instant effects because happiness is an ability that can be “accumulated.”
True happiness is not sudden good luck, but the mental “muscle” you gradually develop through daily practice.
In upcoming articles, we will continue to explore more practical strategies to increase happiness: improving relationships, cultivating mindfulness, engaging in meaningful activities, practicing forgiveness, and more. Each deserves your time and effort for your happiness.
May you live this year with ease, clarity, steadiness, and abundance, experiencing true happiness through continual growth.
