That is nothing at all like happiness. Are you one of those people without emotions? It's OK, I was too for a long time. It happens a lot to people in tech, or people who end up in tech.
Anyways, happiness is an innate emotion. It's much more central than anything about "achieving" your goals. If you don't feel stressed about the future, don't wish you were somewhere else/someone else/doing something else constantly, if you are having your psychological needs met, you are happy. Goal-based happiness is almost as bad as money-based happiness. You have to be more well-rounded than just focusing on your goals.

Haha. Healthy people have emotions for reasons. If you don't introspect about why you are happy, sad, content, enraged, or depressed, you will have less information about how well you are living your life according to your own standards.

It's not clear to me how something could be more central than goals, so I don't think we're using the term "goal" in the same way.
"You have to be more well-rounded than just focusing on your goals."
You are confusing a sense of accomplishment for happiness. That suggests that you may not have felt happiness enough (or recently enough) to recognize it.
