Knowing One's Limitations

Only when one sees his limitations clearly can he begin to understand the nature and quality of his intellect. A man has to know his limitations. For if he doesn't, he will govern himself as a fool, always believing what he sees, always thinking he can handle what comes, never able to look carefully at what he doesn't know (and what it will take to know it), never able to anticipate how his shortcomings may encumber him.
