Upon this life-plan, this foundation, man may erect any superstructure of religion or philosophy that he conscientiously can erect; he should add to his equipment for living every shred of strength and inspiration, moral, mental or spiritual that is in his power to secure. This simple working faith is opposed to no creed, is a substitute for none; it is but a primary belief, a citadel, a refuge where the individual can retire for strength when the battle of life grows hard. A mere theory of life, that remains but a theory, is about as useful to a man, as a gilt-edged menu is to a starving sailor on a raft in mid-ocean. It is irritating but not stimulating. No rule for higher living will help a man in the slightest, until he reach out and appropriate it for himself, until he make it practical in his daily life, until that seed of theory in his mind blossom into a thousand flowers of thought and word and act. If a man honestly seeks to live his best at all times, that determination is visible in every moment of his living, no trifle in his life can be too insignificant to reflect his principle of living. The sun illuminates and beautifies a fallen leaf by the roadside as impartially as a towering mountain peak in the Alps. Every drop of water in the ocean is an epitome of the chemistry of the whole ocean; every drop is subject to precisely the same laws as dominate the united infinity of billions of drops that make that miracle of Nature, men call the Sea. No matter how humble the calling of the individual, how uninteresting and dull the round of his duties, he should do his best. He should dignify what he is doing by the mind he puts into it, he should vitalize what little he has of power or energy or ability or opportunity, in order to prepare himself to be equal to higher privileges when they come. This will never lead man to that weak content that is satisfied with whatever falls to his lot. It will rather fill his mind with that divine discontent that cheerfully accepts the best,--merely as a temporary substitute for something better. The man who is seeking ever to do his best is the man who is keen, active, wide-awake, and aggressive. He is ever watchful of himself in trifles; his standard is not "What will the world say?" but "Is it worthy of me?"
