That complexity is just the fluff around the fear of not surviving.
Some of the stuff you are saying John Smith sounds a bit like self dislike.
I agree with you that most complex issues people may have, probably stem from some pretty basic deep down issues. And that complexity in thought or manner is a by-product of avoiding these issues in daily life due to fear.
And as for thinking about death and being afraid of death. The thought occurred to me on the john today at work, (a really good place for thinking
). That saying we are all going to die yada, yada, yada is a bit of a cop out. Aren't you saying "what does it matter if I piss about and don't care, we are all going to die anyway, and there will be the big crunch later on and the universe won't exist so what is the point?." If you have that kind of approach I can understand why you think about fear a lot.
I personally don't believe in the afterlife I think I will be only dust in the end, optimistcally an oak tree would be nice. Although if I think of my life as eternal (as a thought experiment) then I immediately want to take responsibility for all aspects of it and I feel more calm and less fearful. I like this feeling and so I will continue to adopt this mindset and see how it goes. Hopefully it will be good for me.
I don't want to sound preachy or anything, (I know I do), but I just mean it is the hardest thing in the world to be a well rounded, responsible, healthy person, and I hope someday to describe myself like this. And blasting people for having kids (it is the product of fear don't you know?) is just *not* the way to go about things in my opinion.
