Luck means that an event has no cause at all. It is a bad word; a heathen term. Drop it from your vocabulary! Trust nothing to luck, and expect nothing from it. Avoid all practical dependence upon it or its kindred words, fate, chance, fortune.
Never forget your dependence upon God. He can exalt you to prosperity or sink you into the lowest depth of adversity. He can make everything to which you set your hand to prosper or to fail. Devoutly acknowledge this. Abhor the atheism that shuts God out of His own world!
