If one's bowels move, one is happy, and if they don't move, one is unhappy. That is all there is to it.

Where there are too many policemen, there is no liberty. Where there are too many soldiers, there is no peace. Where there are too many lawyers, there is no justice.

So much of unhappiness, it seems to me, is due to nerves; and bad nerves are the result of having nothing to do, or doing a thing badly, unsuccessfully or incompetently. Of all the unhappy people in the world, the unhappiest are those who have not found something they want to do. True happiness comes to those who do their work well, followed by a refreshing period of rest. True happiness comes from the right amount of work for the day.

Of all the unhappy people in the world, the unhappiest are those who have not found something they want to do.

In fact,I believe the reason why the Chinese failed to develop botany and zoology is that the Chinese scholar cannot stare coldly and unemotionally at a fish without immediately thinking of how it tastes in the mouth and wanting to eat it. The reason I don't trust Chinese surgeons is that I am afraid that when a Chinese surgeon cuts up my liver in search of a gall-stone, he may forget about the stone and put my liver in a frying pan.
