How important is education when you already know?

Question

(-:

Answer 1

Sorry, no one ever knows everything. You could live 1,000,000 years and still not know everything about everything.

I try to learn something new every day. Yet, I haven't even scratched the surface of so many subjects.

If you stop learning you are either deluding yourself or dead.

Answer 2

My experience with those who already know is that they don't, and a little education would confirm it.

Answer 3

You must be really really clever. If you know everything, what am I having for my tea tonight?
