Ah, a nihilist. I know my limits, and virtually nothing I can say will change your mind because it’s still closed, and you likely already have an answer to any questions you ask.

You can see it as naive and idealistic, and sure, I get it. But I never claimed happiness is permanent. It’s a worldview, and those can and should change. How they change is entirely up to the individual.
You have more control over your path than you realize, and those who benefit from a defeated or complacent populace are terrified of you realizing it.
