It is really useful to be reminded of your errors. I think Warren Buffett and I are pretty good at that. We do kind of mentally rub our own noses in our own mistakes. And that is a very good mental habit.
We all are learning, modifying, or destroying ideas all the time. Rapid destruction of your ideas when the time is right is one of the most valuable qualities you can acquire. You must force yourself to consider arguments on the other side.
