"Neither let mistakes and wrong directions - of which every man, in his studies and elsewhere, falls into many - discourage you. There is precious instruction to be got by finding that we are wrong. Let a man try faithfully, manfully to be right, he will grow daily more and more right. It is, at bottom, the condition which all men have to cultivate themselves. Our very walking is an incessant falling - a falling and a catching of ourselves before we come actually to the pavement! - it is emblematic of all things a man does."
