We must always choose to do what we have the opportunity to do. A great proportion of the opportunity is to be prepared for it. We do not know when it is going to come or what it will look like, so we must prepare in every possible way. Being prepared is what makes us sensitive to recognizing the opportunity. We invoke the opportunity when we work on preparing for it. The more prepared we are, the more chances there are that the opportunity will appear, and appear again.
