By accepting the fact that life is inherently meaningless, and that the best attribute of being a human is the ability to create and find our own meaning in life.
We give ourselves the meaningfulness in our lives - friends, family, love, duty, creativity, politics, faith, hobbies… anything that we find fulfilling and making life worth living. Even the smallest and seemingly shallow purposes can be just as powerful as the biggest and grandest purposes - it’s all up to us to find out the ones that keep us going and happy. It’s not easy, it never ends, but the struggle to improve and live life happily is a beautiful thing.
