IS IT ALL BULL SHIT?

I just got a birthday card that shows a little girl looking up at God and asking WHAT IF IT'S ALL BULL SHIT?
I have been thinking about that phrase and perhaps in an existentialist way it IS all bull shit. We care so much; we do so little; we hate; we love; we work to achieve and fail to accomplish, we win prizes, we lose face and what does it all amount to in the long run? I guess if you believe as I do that when you are dead, you are dead and when a thing has happened it has not happened for any reason greater than that it did happen, you lose the sense of a greater meaning to life.
I guess it all IS a lot of bull shit in the cosmic sense but in the moment to moment of life it is not.... at least not for me. I am living today and loving it or sometimes wishing today would hurry up and be tomorrow. I am building every today to make a better tomorrow FOR ME not for the world not for my next life and not to make up for the lives I lived badly
I am not sure this is a good thing but I am pretty sure it is what is.
Would I feel differently if I were in a relationship. Would I feel differently if I had children? I don't know. But for me, single and surviving, the only thing that really matters is the now I have and the now I prepare for tomorrow.
