I do not know everything; still many things I understand.

Know a little about a lot.

I know more than I can express in words, and the little I can express would not have been expressed, had I not known more.

I know a little bit about a great many things and not enough about any one to make a living in these times.

I know too much and not enough

I don't pretend to be wise, but I am observing, and I see a great deal more than you'd imagine. I'm interested in other people's experiences and inconsistencies, and, though I can't explain, I remember and use them for my own benefit.

...The more I learned the more I realized how very much one has to know before one is in-the-know at all.

I'm not a genius. I'm just a tremendous bundle of experience.

I don't give advice, but I've got a lot of information to share.

If it seemeth to thee that thou knowest many things, and understandest them well, know also that there are many more things which thou knowest not.

The more I learn, the more I realize how much I don't know.

I don't profess to be profound; but I do lay claim to common sense.

You know more than you think you know, just as you know less than you want to know.

I am enormously wise and abysmally ignorant
