Ecclesiastes 4:4-6

I realized the reason people work hard and try to succeed: They are jealous of each other. This, too, is useless, like chasing the wind. Some say it is foolish to fold your hands and do nothing, because you will starve to death. Maybe so, but I say it is better to be content with what little you have. Otherwise, you will always be struggling for more, and that is like chasing the wind.
