I read your link and honestly have NFI what it is trying to say actually IS nihilism. There's a lot of comparisons with various character traits though.

My view is more the existential nihilism: https://en.wikipedia.org/wiki/Nihilism

"""This view suggests that it is not possible to live a genuinely meaningful life, that there is no higher reason to continue living, and that all efforts, achievements, happiness, and suffering are ultimately pointless"""

My first sentence is kind of how I reason that point. There is no "ultimate" reason for being because given sufficient time, any reason you might have, doesn't matter.

Then there is my reaction to that: I'm here. So now what?

Some people may commit suicide.

Some may go on a rampage hurting people.

If there is no higher power then I get to choose my purpose in life and no one can say it is any better or worse than anything else to do. So I figure (reasons not shown which may be the more interesting conversation...); live, be nice, be curious, do cool things.

I acknowledge my upbringing and privileges are a significant influence on my day-to-day choices too. But so what? If there is no higher power to judge...

Hopefully I'll enjoy life - no major complaints so far - which if nothing else, feels nice. I guess you could argue I'm some level of hedonist. But so what if I am?
