There is the mistake of overdoing the defense of the status quo, the error of “don’t change what is not broken”, the error of investing too much time and energy in keeping things as they are.

The “this is how we do things around here” mistake.

And then there is the mistake made while inventing the future, the error of small experiments gone bad.

We are almost never hurt by the second kind of mistake and yet we persist in making the first kind, again and again.
