Ecclesiastes 9:6-10

Indeed their love, their hate, and their zeal have already perished, and they will no longer have a share in all that is done under the sun.

Go then, eat your bread in happiness, and drink your wine with a cheerful heart; for God has already approved your works.

See that your clothes are white all the time, and that there is no lack of oil on your head.

Enjoy life with the wife whom you love all the days of your futile life which He has given you under the sun, all the days of your futility; for this is your reward in life and in your work which you have labored under the sun. Whatever Your Hand Finds to Do

Whatever your hand finds to do, do it with all your might; for there is no activity, planning, knowledge, or wisdom in Sheol where you are going.
