A movie named "Tootsie" came out 25 years ago. At the beginning, we see a series of short scenes. Dustin Hoffman is a moderately successful career actor who also teaches acting. We see scenes of him lecturing his students: The director rules, the director is god, you are there to obey the director, and these are interleaved with scenes of him at work arguing with directors, insulting directors, telling off directors, swearing at directors and stomping off the job, etc.

Lesson? The needful things we are most aware of are often the things we are worst at, and we're often quite unaware of our failure.

Corollary? Wisdom requires a large amount of uncomfortable and even ruthless introspection, which taxes anyone's capability at being objective. Ol' Dustin really believed what he was telling his students. But when the director was an idiot, that took precedence anyway. Dustin would have condemned himself if he had even realized.
