It is not that unsuccessful people never see opportunities; they do. But they differ from people who are called winners in that they rarely have the will or the courage to act on a good idea. They give themselves only the reasons why something could not be done, while the winner only thinks of how it could.
Always imagine the best possible outcome, and the forming of reality will follow the design.
If you have a single powerful purpose, you will have the courage to act on your ideas.
