Happiness? What is it really?

Everyone seems to have a view on what happiness is. The best minds have pondered its true nature for some thousands of years. Happiness is no laughing matter. And what about other emotions? The so-called "negative" emotions? Are they to be shunned as the black sheep of the fold of emotions? I believe they are valuable as happiness, and all are there to guide us.

I have reviewed the matter from many angles - spirituality, mysticism, psychology, cosmology, neurobiology, religion, modern and ancient philosophy... and took the view that they all had something important to say. This short clip picks out one feature of my conclusions.
