Ecclesiastes 9:7-10

Go ahead — eat your food and be happy; drink your wine and be cheerful. It's all right with God. Always look happy and cheerful. Enjoy life with the woman you love, as long as you live the useless life that God has given you in this world. Enjoy every useless day of it, because that is all you will get for all your trouble. Work hard at whatever you do, because there will be no action, no thought, no knowledge, no wisdom in the world of the dead — and that is where you are going.
