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.

Reality, if rightly interpreted, is grander than fiction.

He that has a secret should not only hide it, but hide that he has it to hide.

Wondrous is the strength of cheerfulness, and its power of endurance - the cheerful man will do more in the same time, will do it; better, will preserve it longer, than the sad or sullen.

The errors of a wise man are literally more instructive than the truths of a fool. The wise man travels in lofty, far-seeing regions; the fool in low-lying, high-fenced lanes; retracing the footsteps of the former, to discover where he diviated, whole provinces of the universe are laid open to us; in the path of the latter, granting even that he has not deviated at all, little is laid open to us but two wheel-ruts and two hedges.
