Energy will do anything that can be done in this world; and no talents, no circumstances, no opportunities, will make a two-legged animal a man without it.
We should act with as much energy as those who expect everything from themselves; and we should pray with as much earnestness as those who expect everything from God.
The shortest and surest way to prove a work possible is strenuously to set about it; and no wonder if that proves it possible that for the most part makes it so.
Strong impulses are but another name for energy. Energy may be turned to bad uses; but more good may always be made of an energetic nature, than of an indolent and impassive one.
He who would do some great thing in this short life must apply himself to the work with such a concentration of his forces as, to idle spectators, who live only to amuse themselves, looks like insanity.
No conjunction can possibly occur, however fearful, however tremendous it may appear, from which a man by his own energy may not extricate himself, as a mariner by the rattling of his cannon can dissipate the impending waterspout.
