I may be smart, but I'm not knowledgeable.

Nobody is smarter than you are. And what if they are? What good is their understanding doing you?

My mind is a collection of truths that I have extracted from greatest thinkers throughout human history

Work hard AND smart.

I can hardly keep track of the things I don't know, but every now and then comes an ignorance that makes me nostalgic.

There are too many literati, yet very few are smart; knowledge is acquired far too easily.
