I don't expect others to feel the same. I have chosen to give value to one over the other simply because I would prefer a world where we collaborate towards collective happiness, joy, and pleasure. I suspect many others believe that working towards the prosperity of the collective will hamper their ability to find personal prosperity, and I simply think they are wrong. I think such a case boils down to chasing momentary pleasure over long-lasting pleasure, because that is my experience with such people.

In a way I believe in tangible karma; those who work to bring pleasure to those around them are occasionally taken advantage of, but more often are given pleasure in turn. Likewise, I've never met a self-centered asshole who isn't consistantly overcome with unhappiness, while almost universally blaming that unhappiness on external factors.

I plant trees I will never get to sit under because I appreciate those before me who did the same. Again, that is no more than what I have chosen to give value to.

But this is a bit of a digression. The reality is these are the wisdoms of my experiences, and I wager there's no universal truths in them. Nothing matters, so I look to these experiences and see that a co-operative, collaborative life looks more pleasurable. So I strive towards one, encourage others to do the same, and refuse to tolerate those that would actively work to steal happiness from others. Yes, I am aware that the inverse is equally true - why is it wrong to steal happiness from others if nothing matters - but this perspective is simply not the one I have chosen to place value on. Arbitrary? Sure. It still represents the best way I've found to enjoy life.

I don’t think there’s a purpose, really; to put purpose or duty to a sense of joy is to try to quantify it, to package it - and since everyone is different, and perceives things differently, then that means joy takes just as many different forms and can’t be packaged so neatly.

I think life in every sense is more chaotic than that, and that randomization of cells or events or emotions can’t and shouldn’t be whittled down into some universal experience or explanation. Making something your “purpose” immediately brings with it a certain expectation - it almost makes it sound as if you’re trying to be happy out of duty, which seems…weird.

I don’t think you’re failing at life if you’re unhappy. Everyone has low or weak points, and that inevitably changes in some form of another. That’s one of the universals, a product of events and living situations and hormonal/genetic makeup. Sometimes people can have all their needs cater to and still your brain will fuck you over.

So I’d ask yourself why you’re looking for a purpose in the first place. It makes sense if there’s some goal you want to attain; and if that goal is happiness, it’d be best to think about some actions you could do to obtain it. If you’re not looking for that goal and just asking why people seem to pursue happiness, then the best answer I can give you is: why not? Suffering feels bad and I don’t wanna feel bad.
