15 So I think that we should enjoy our lives. People should be happy to eat, drink and enjoy their lives. That is the best thing for them to do. It will help them to enjoy the work that they do during their lives. That is the life which God has given them on the earth.
16 I tried very much to become wise. I wanted to understand the things that people do on the earth. People work in the day and in the night and they do not sleep. 17 I thought about everything that God has done. I realized that nobody understands everything that happens on the earth. Even if they try very much, they will not know everything. A wise person may say that he understands all these things. But really that is not possible.
