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.
