Feynman, in his freshman lectures, had some topic (I don't remember what) that he wanted to use as a topic. But he couldn't figure out how to explain it to freshmen. He said, "That means we don't really understand it."
Although when I was younger I took it too much to heart and became obsessed with having a verbal and written understanding of everything when, sometimes, a deeper understanding at a subconscious, more intuitive, level is more useful. :)
