Luck is the time when preparation and opportunity meet. When you're prepared, your chance for success will come. You can change chance into good fortune if you're ready. By the law of periodical repetition, everything which as happened once must happen again and again and again. Not capriciously, but at regular periods, and each thing in it's own period, and each obeying it's own law. There is a tide in your affairs, when taken at the flood, that will lead you on to fortune. As events tend to repeat themselves, the tide of opportunity will come to you. The only sure thing about luck is that it will change.
