[I]n the years we have developed enormous abilities in mathematics and it takes a long time to train the students, and so they're very highly educate… - Richard Feynman

"And then I thought to myself, "you know, what they think of you is so fantastic, it's impossible to live up to it. You have no responsibility to live up to it!"
It was a brilliant idea: you have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing."

"It was a kind of one-upmanship, where nobody knows what's going on, and they'd put the other one down as if they did know. They all fake that they know, and if one student admits for a moment that something is confusing by asking a question, the others take a high-handed attitude, acting as if it's not confusing at all, telling him that he's wasting their time... All the work they did, intelligent people, but they got themselves into this funny state of mind, this strange kind of self-propagating "education" which is meaningless, utterly meaningless."

I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to have answers that might be wrong.
