How do you know how much your worth is?

Why do I even bother to know anything at all? I know things because I need those information to survive. So, I like to think that I worth more than all that I know. And that I need to know more, to protect that essence that I consider worth the effort of knowing more.

So, I cannot think I worth any less than the highest worth I can associate with any object. Since otherwise, that piece of knowledge won't serve the purpose that my knowledge is supposed to serve.

Thus, knowing my worth is contrary to the whole purpose of knowing! It follows from the fact "the concept of quantitative worth is relative" that I have to grant infinite worth to others, as well.
