"The best that people can do is eat, drink, and enjoy their work. I saw that even this comes from God."
Ecclesiastes 2:24 NCV
Contentment comes from finding joy and satisfaction in our lives and in our work, and in our desire to please God. It is not found by continually desiring, reaching for, or seeking the "greener pastures" of greater wealth and "building bigger barns" to fill with things that don't last.
