Thinks like this.  

But the thing is that it is all meaningless. You can create all you want, you can be all knowing, you can be God himself but in the end we'll all die. We'll be forgotten and nobody will care. Because in the end everything comes to nothing. You'll die too. Everything will cease to exist. The things you created will come to an end. All of it will be meaningless. The stars will blow up and the whole universe will die. You'll be forgotten as if you never existed.
