Your goal should be to leave a larger than life footprint on earth, other that that life is completely meaningless and bullshit waste of time and space.
Being a Schwarzenegger, Obama or Zuckerberg is what life is about, changing that fucking planet fundamentally, so try and spend every waking minute of your fucking day to make something happen noone has done before. Die trying that, and, no matter if you achieve it or not, and your life will be fulfilling!
