Virtue means doing the right thing, in relation to the right person, at the right time, to the right extent, in the right manner, and for the right purpose. Thus, to give money away is quite a simple task, but for the act to be virtuous, the donor must give to the right person, for the right purpose, in the right amount, in the right manner, and at the right time.
AristotleThe activity of happiness must occupy an entire lifetime; for one swallow does not a summer make.
AristotlePoliticians also have no leisure, because they are always aiming at something beyond political life itself, power and glory, or happiness.
Aristotle
