Introduction: What Is True Happiness?

Happiness isn’t just about fleeting moments of joy—it’s about long-term fulfillment, well-being, and emotional resilience. But how do we achieve it?

🔹 A study by Harvard University, known as the Harvard Study of Adult Development, found that the biggest predictor of long-term happiness is strong relationships, not money or success.

The Science Behind Happiness

🔹 Neuroscientists at the University of California found that happiness is influenced by brain chemistry, genetics, and life choices.

✔ Our brains release dopamine, serotonin, and oxytocin, also called the "happiness chemicals", which shape our emotional state.

✔ A study in the Journal of Happiness Studies found that 40% of happiness is under our direct control, while 50% is genetic and 10% depends on life circumstances.

This means we can actively increase happiness by changing our mindset and daily habits.
