Ecclesiastes 2:15-19

Finally, I said to myself, “Being wise got me nowhere! The same thing will happen to me that happens to fools. Nothing makes sense. Wise or foolish, we all die and are soon forgotten.” This made me hate life. Everything we do is painful; it's just as senseless as chasing the wind. Suddenly I realized that others would some day get everything I had worked so hard for, then I started hating it all. Who knows if those people will be sensible or stupid? Either way, they will own everything I have earned by hard work and wisdom. It doesn't make sense.
