Before opportunity crowns you with great success, it usually tests your mettle through adversity.
Adversity provides the resistance necessary to develop the strength to overcome great obstacles. This strength consists of self-confidence, perseverance, and, very importantly, self-knowledge. For if you do encounter a setback, it is a clue to a personal weakness. You may have been hasty in judging a competitor, or you may have been too timid in your vision of what needed to be done. Let adversity be your guide to understanding where you mis-stepped and which qualities you need to cultivate. No one rejoices in disappointment, but if you are success-conscious, you can turn the situation into a chance for improving your character, an opportunity you otherwise would have missed.
