To realize that you were mistaken, is just the acknowledgement , that you are wiser today than you were yesterday.
Johann Kaspar LavaterThe prudent see only the difficulties, the bold only the advantages, of a great enterprise; the hero sees both; diminishes the former and makes the latter preponderate, and so conquers.
Johann Kaspar LavaterHe who always seeks more light the more he finds, and finds more the more he seeks, is one of the few happy mortals who take and give in every point of time. The tide and ebb of giving and receiving is the sum of human happiness, which he alone enjoys who always wishes to acquire new knowledge, and always finds it.
