I told myself, "I have become a great man, far wiser than anyone who ruled Jerusalem before me. I know what wisdom and knowledge really are."

The wiser you are, the more worries you have; the more you know, the more it hurts.

I will do what you have asked. I will give you more wisdom and understanding than anyone has ever had before or will ever have again.

I decided to enjoy myself and find out what happiness is. But I found that this is useless, too.

It is useless, useless, said the Philosopher. Life is useless, all useless.

I have seen everything done in this world, and I tell you, it is all useless. It is like chasing the wind.
