And excellence is in doing unreasonably more than necessary.
Example. I just wrote a thing for work, supposedly. Probably put 20 hours into a one hour job. That work made me happy. And already I am thinking of ways to make it better.
I will hit publish (metaphorically speaking) on it now. The improvements are embellishments, additions.
My point is that I am deeply satisfied with having put an unreasonably excessive effort into something trivial. But not trivial! It is a clean explanation that will enlighten others and will make their lives easier. The time and effort gave me a deeper understanding of the subject.
And it gave me a behavior model to follow.
