The original sentence of the famous saying in Nietzsche's Records of Last Words
Nietzsche said, "Living makes you want to live again. It is your responsibility to live like this." (Records of Last Words) Life is only a few decades, so why not be happy? Even if life always encounters painful and unfortunate things. It is the theme of life to despise pain with happiness! In order to "desire to live again", take "your responsibility"!
