Ecclesiastes 2:12-15

[12] So I turned to consider wisdom and madness and folly; for what can the man do who comes after the king? Only what he has already done.
[13] Then I saw that wisdom excels folly as light excels darkness.
[14] The wise man has his eyes in his head, but the fool walks in darkness; and yet I perceived that one fate comes to all of them.
[15] Then I said to myself, "What befalls the fool will befall me also; why then have I been so very wise?" And I said to myself that this also is vanity.
