I tend to shy away from all the isms,, communism, socialism, pessimism, futurism, watchtowerism, to name a few. But if one is desperate for a purpose and meaning in life then choose one and see.
I tend to see this as a personal issue and varied responses depending on ones religious indoctrination, cultural conditioning, as well as education. I tend to find life a mystery and the question of purpose very subjective in nature so I do not use my brains cells to process the question as it would be meaningless in my estimation and because I got a lot on my plate/mind right now with all the information I'm getting on the internet to process.
Not saying it is a complete waste of time, just for me it is presently maybe when on on my deathbed I'm might ponder it more as I head to that great computer in the sky and download all my data.
