Even in the most dismal of times, there are things that need to be done. Opportunity is always present, but it is rarely obvious. To be lucky, you must learn to look at a situation and see opportunity where others see nothing. It requires a certain amount of detachment, so you can view your situation without being clouded by emotion. It requires the courage to try something completely new and the confidence to follow your own path.
Lucky people are also the ones who are prepared for opportunity.
Being prepared primarily requires discipline. Discipline is not easy. It requires that you put out sustained effort over a long period. It takes discipline to learn new skills, to accumulate capital, and to make new contacts. And these are the kinds of things you'll need to take advantage of the opportunities you discover.
