Quotation

[madam_ray]

"It is hard work to be excellent, since in each case it is hard work to find what is intermediate; e.g. not everyone, but only one who knows, finds the midpoint in a circle. So also getting angry, or giving and spending money, is easy and everyone can do it; but doing it to the right person, in the right amount, at the right time, for the right end and in the right way is no longer easy, nor can everyone do it. Hence [doing these things] well is rare, praiseworthy and fine."

- Aristotle, Ethics.
