Ecclesiastes 9:7-10

7 Go your way--eat your bread with joy, and drink your wine with a merry heart; for God has already accepted your works. 8 Let your garments be always white, and don't let your head lack oil. 9 Live joyfully with the wife whom you love all the days of your life of vanity, which he has given you under the sun, all your days of vanity: for that is your portion in life, and in your labor in which you labor under the sun. 10 Whatever your hand finds to do, do it with your might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, where you are going.
