Life always offers you a second chance. It is called tomorrow.
You are a young man deeply unsatisfied with your life. Your life really is not that terrible, but you enjoy pretending it is. Your self-conjured gray cloud of pessimism follows you around everywhere you go because it is your only shelter from the cognizance that you may truly be insignificant in this world. You live in anticipation for the day that will change your life, as if some incomprehensible natural order were secretly rooting for you to unleash your untouched potential. Of course, you are not doing anything to make that day come sooner. It is easy to wait for the sun to come out when the patterns of the solar system require no additional effort on your part.
