There is no such thing as perfect happiness. Then perfect knowledge. Although, with a little bit of knowledge, I am already very happy. Nothing has to be perfect, as long as you're happy.
I think that with the perfect knowledge of anything and everything, you can have the ability to become perfectly happy. If you understand how everything works, from consciousness to energy, I think you can control that too.
I think it is the desire of many people, to feel happy with what one is, with what one has would be the motto, I think that the nature of the human being is to exploit that feeling to its fullest expression, although there are many factors that we continuously encounter so that this is not a reality
Actually, neither of them, because both are boring. although I would always improve people, I suspect. That, in turn, makes me unhappy, so I chose happiness anyway.
If you'd rather have perfect knowledge, I think I can make my luck with that, eventually. I would then share this with others around me, make myself meaningful. And then, in my opinion, I am also perfectly happy.
