Think of it this way: admitting that you are wrong is nothing more than adjusting your navigation on the path of rightness. But if you do not make such navigational adjustments, in the end you will be more wrong, and more off the path, and have to work that much harder to counteract your stubborn behaviors.

Apologizing is an artform, and it gives you power. Think of your sensei, Ferrett. When he is wrong, he admits it. When he crosses the line, he apologizes. So his words have more gravitas when he sticks to his guns, because you know it's not just out of stubbornness.

You name all things that I currently struggle with. I suppose it is time for a change in my philosophy.

Sounds like the source for a New Year's Resolution to me....
