We ought not to confine ourselves either to writing or to reading; the one, continuous writing, will cast a gloom over our strength, and exhaust it; the other will make our strength flabby and watery. It is better to have recourse to them alternately, and to blend one with the other, so that the fruits of one's reading may be reduced to concrete form by the pen.
Seneca the YoungerNo man is born wise; but wisdom and virtue require a tutor; though we can easily learn to be vicious without a master.
