In the end , nothing matters.

  The cosmic perspective: At some point,you will die. Your children will die. Your friends will die.Everyone who knows you,likes or hates you,will die too. After 100,1000,10000 years,no one will remember you. Absolutely no one.source:scientia.ro
  It's hard to live when you  realise this perspective is true.No matter how many times you tried to deny it,it is true.Nothing can change it.Everything has an end.You can work hardly , it doesn't matter.Your actions are worthless.Your Facebook likes/comments are worthless.Your fame is worthless.Everything is worthless.Your feelings,thoughts,actions will be forgotten.
  There's nothing supernatural that created you,you were made from star dust.You will become a stardust.You evolved from something inferior .Something supperior will evolve from your species.Despite everything is in a continue movement ,evolution ,development,we will end.The Earth will end.We're not sure how,maybe a collision with an asteroid,maybe a nuclear explosion or another World War.Our Sun will end,by running out of hydrogen.(or a Black Hole will "swallow" our Solar System)Our Galaxy will reach the finish line, by colliding with the Andromeda Galaxy(or maybe another one).The Universe will collapse.
  Live your life,don't be afraid of Hell, don't hope to go in Heaven.Sin or not, is your choice.But don't forget , the Universe has no mercy.It will burn us all , it will turn us in star dust!
