I Am Smart Enough to Know I Don't Know It All

Of Course I Don't Know It All.... I understood that a long time ago.
I actually came up with a saying to clarify my true knowledge. Instead of saying I know something, I say "I think I'm beginning to understand..." so-and-so. I'm understanding a certain perspective of a subject that I may or may not properly recognize the true significance of. And I have no idea what I just meant by my last statement.
