What do you believe life really consists of? What is life to you?
It depends on what "life" you're referring to.
Do you mean the stage that living organisms are in before Mort delivers them divine tranquility or my take on the human way of life?
If you mean the latter, I initially was a nihilist, an existential nihilist to be precise. My sole purpose in life is accumulating knowledge, & as your knowledge reservoir improves, your happiness recedes. And the meaning of life for us as metaphysical beings boils down to happiness, a mere production of a number of endorphins. I've been through a stage where all of existence was meaningless to me, let alone beliefs. I believe that we, human beings, are unlikely to bring any change in this undefined universe & there is no objective reason for our intrinsic existence as our subjective selves make it out to be. Just evolved bundles of fibre with enough intelligence to question our existence despite there not being any philosophical reason to it. Hence, our existence is null & void.
I've come to the conclusion that nihilism is too try-hard a concept & will forever leave me suicidal so I'd rather say that I'm not qualified to answer the question.
