Ecclesiastes 9:7-10

7Go, eat your food with gladness, and drink your wine with a joyful heart, for God has already approved what you do. 8Always be clothed in white, and always anoint your head with oil. 9Enjoy life with your wife, whom you love, all the days of this meaningless life that God has given you under the sun—all your meaningless days. For this is your lot in life and in your toilsome labor under the sun.

10Whatever your hand finds to do, do it with all your might, for in the realm of the dead, where you are going, there is neither working nor planning nor knowledge nor wisdom.
