As a sidenote, the reason I became a minimalist, when about medicine, is that I have seen, time and again, that the greatest doctors know not what to do, but what not to do.
"Don't just do something, stand there!" was the favorite saying of one of the oldies from my fellowship. First do no harm. The best (private) surgeon I know has canceled cases on the day of surgery ("you don't need surgery anymore"). Again, FIRST DO NO HARM!
This thread is a poster case for minimalism.
