That we are going to die. You either hustle, slow down, lay down, back down, run, walk, stop, be successful, do not be successful, fail, succeed, fall down, stand again, be good, be bad, be kind, be arrogant, everything is going to go back to ZERO. And you will die.
Now decide, if you want to make this world a better place for future generations before you die? or you want to keep your shitty arrogance with you till someone burn you into ashes.
