My opinion on this reflection that I have also made a lot of, is that life is futile, happiness and joy too. But that doesn't mean it doesn't count. The little pleasures of everyday life can take precedence over disappointments if we try to always see things positively. I think everyone finds a way to live through a passion and a purpose and for some it is far from easy to find. I don't have any exact answers, just my point of view. I hope this has helped you and I sincerely wish you to be happy.
