Do not look to your work for ultimate meaning and satisfaction, because:
1. Our possessions will be left to someone else who may be unwise, and who didn't work for it. (2:18-21)
2. Our days will be filled with sorrow, and our nights will be restless. (2:22-23)
But...
3. As those who please God, enjoy what you do as a gift from God. (2:24-26)
