Because this is our first life

No one ever said that life has a respawn button that whenever you die,you can just live another life again. Fate only gives us this life to live so no one arent considered to be wise nor amateurs in this life since all of us are living this life for the first time.
Maybe the term YOLO is correct, "You Only Live Once" so therefore we need to appreciate what life can offer. Instead of bashing the things that we hate in this life why not promote the things and the people that we love. That isnt too complicated right?
