It is most important to allow the brain the full measure of sleep which is required to restore it; for sleep is to a man's whole nature what winding up is to a clock.
We must set limits to our wishes, curb our desires, moderate our anger, always remembering that an individual can attain only an infinitesimal share in anything that is worth having; and that on the other hand, everyone must incur many of the ills of life

Nothing in life gives a man so much courage as the attainment or renewal of the conviction that other people regard him with favor; because it means that everyone joins to give him help and protection, which is an infinitely stronger bulwark against the ills of life than anything he can do himself.
Personal courage is really a very subordinate virtue-a virtue, indeed, in which we are surpassed by the lower animals; or else you would not hear people say, as brave as a lion.
