Prophex,
You have too much time and not enough problems in your life.
When you start having to struggle to pay the bills, your wife's having an affair and you're waiting for the results of that scan to verify whether the tumour in your abdomen in benign or not, all this meta-physical wondering will become utterly insignificant.
You'll be striving to do the things you enjoy and avoid the things you hate.
Your life will be full of meaning, as simply as that.
Until then....
"In life, you have to face that some days you'll be the pigeon and some days you'll be the statue."
