Be master of your petty annoyances and conserve your energies for the big, worthwhile things. It isn't the mountain ahead that wears you out - it's the grain of sand in your shoe. - Robert Service
Take patiently the petty annoyances, the trifling discomforts, the unimportant losses which come upon all of us daily; for by means of these little matters, lovingly and freely accepted, you will give Him your whole heart, and win His. - Francis de Sales
