You really don't. Out of the 7 billion people on the Earth right now, what makes you special? In fact even if you did do something worth while is it worth anything? In the end you'll die like everyone else and go to Heaven or Hell. God made us all different and unique, but we choose to live mediocre lives that are sad and meaningless. Spending our times arguing over who's the best canindate. Why Conservitives are worse than Liberals. No one cares about you or your opinion. I mean God might care if you have seen your sin, and you've found purpose. But I mean come on. Without a God there is no morals, what makes your life worth anything. Even are emotions can be deconstructed by science. Million of people have lived a variation of your life. Of my life. We're all going to die, so find something to live for okay? We matter to our friends and family. We matter to God. Edit: I was being edgy and stupid. Please forgive me for acting like this.
