Education doesn’t make you happy. Nor does freedom. We don’t become happy just because we’re free – if we are. Or because we’ve been educated – if we have. But because education may be the means by which we realize we are happy. It opens our eyes, our ears, tells us where delights are lurking, convinces us that there is only one freedom of any importance whatsoever, that of the mind, and gives us the assurance – the confidence – to walk the path our mind, our educated mind, offers.
I'm afraid that we all make mistakes. One of the things that defines our character is how we handle mistakes. If we lie about having made a mistake, then it can't be corrected and it festers. On the other hand, if we give up just because we made a mistake, even a big mistake, none of us would get far in life.
