"We have no reliable guarantee that the afterlife will be any less exasperating than this one, have we?"

Noel Coward's quote is a tip that life is unforeseeable which we can never ensure what lies ahead. He is suggesting that the afterlife might not be any much better than this life, which we ought to not take anything for granted. He is likewise recommending that we should maximize our lives and enjoy the present minute, as we can not ensure what the future holds. This quote encourages us to live life to the fullest and to value the good moments, as we can not be certain of what the afterlife will bring. It is a tip that life is vulnerable and that we should take advantage of it while we can.
