I was thinking recently. It's so easy to communicte when it comes to material realm. Please, pass me the salt. I don't like the blue carpet. Where can I find nearest cinema? But we start to lose to completly when it comes to our inner world. It's such a mess. How many people take time and effort to sort, define and nuance it? Cultural narratives? Even worse. Happiness is so often seen as "good chemical feeling" by the pop culture. Sadness is almost forbidden and feared, so easile connected conceptually with depression. These are so much different qualities.

What's your definition of happiness? Does it encompass sadness or are these mutually exclusive?

I really like your conclusion here though, whatever it is, observe and feel is a way to go.
