Ecclesiastes 11:8-9

8 Be grateful for every year you live. No matter how long you live, remember that you will be dead much longer. There is nothing at all to look forward to.
9 Young people, enjoy your youth. Be happy while you are still young. Do what you want to do, and follow your heart's desire. But remember that God is going to judge you for whatever you do.
