The test of a successful person is not an ability to eliminate all problems before they arise, but to meet and work out difficulties when they do arise. We must be willing to make an intelligent compromise with perfection lest we wait forever before taking action. It's still good advice to cross bridges as we come to them.
The person determined to achieve maximum success learns the principle that progress is made one step at a time. A house is built one brick at a time. Football games are won a play at a time. A department store grows bigger one customer at a time. Every big accomplishment is a series of little accomplishments.
