Yes, it does make us happy. But imagine how boring would it be if every day, every moment was a happy one? What would be the point of learning? We would be aimless. We would be clueless about what to do in our life. Life would stagnate.
Living life is more important than achieving happiness. And it is different from surviving or existing, as many would already know.
Yet, happiness is all that we chase. Although it does serve as a goal in life, but to the point that it gets overrated and we forget to live in the moment, and most importantly, to embrace every experience in life like a step closer to the attainment of wisdom.
