An expert is a person who has made all the mistakes that can be made in a very narrow field.
We can lick gravity, but sometimes the paperwork is overwhelming.
Wernher von Braun
I heard the definition of an expert is to break down the word, an ex is a has been and a spert s a drip under pressure. If you are not learning you are not proficient, none know all.
As for paper work, that is something that even computers cannot end. Nothing is done till the paper work is finished.
I remember hearing that computers were supposed to solve all those endless paper files--and perhaps they have--but I still want a piece of paper in my hands "to have and to hold". :>)
I have more paper now than way back when in the good old times when I had to write down everything or type.
