Happiness can Sometimes be bought

Although man has been searching for an explanation for happiness throughout his life, from the first civilizations, until now, there is no consensus on the concept of this word, which intersects with many other terms, all of which are used to refer to the same concept, such as: the concept of happiness. Satisfaction, adjustment, economic prosperity, well-being, quality of life, but what exactly is happiness?
Happiness means a feeling of joy and enjoyment of life, and it is a relative concept that varies from one person to another according to the priorities and interests of each individual. Does happiness really mean striving towards achieving positivity in psychology? How do you define happiness? What is happiness for you? How do you know you're happy when you find it? And when have you lost it? Is there a deeper and stronger concept of happiness than simply relying on numbers that tell everyone that this country is happy because it is the most prosperous, and another is miserable because it is the poorest and most needy? Is it reasonable to find Arab countries torn apart by conflict and fighting for an entire decade while others have been suffering from occupation for more than seven years? Decades ahead of others in the World Happiness Index this year?
