Observation is key. Words can be untrue. Actions speak louder than words. The goal is maa kheru, to be be true of voice, where your words align with your actions.
The stubbornness and saving face to continue along the wrong path is foolishness. It's better to know as soon as possible when a wrong turn has been made in order to course correct the mistake, to admit "I was wrong".
The alignment of words with actions. That is quite a worthy goal to have and achieve!
