As we have known, most people are too attached to the past, to what they are familiar with. Therefore, they will miss opportunities that stand right in front of them. Doors may close, but there are always other unlimited numbers of doors – new opportunities to get new happiness. Alexander Graham Bell also used to say that: “When one door closes another door opens, but we so often look so long and so regretfully upon the closed door that we do not see the ones which open for us”. The world is full of opportunities if we could only see them. Furthermore, not every plan works out. Successful people today must get the cheese in the past. There are losses and failures, problems in relationships, loss of money or job, and sometimes unpleasant things happen that we can not always have control over them. However, we can exercise control over our attention and attitude of these happenings. When one of these things happens, and we focus our attention on the loss – the closed door, we see only a closed door with the resultant frustration and unhappiness, but if we could only move our sight and attention away from the closed door, we might be surprised to discover a row of openning new doors. To sum up, I just want to say: Do not try to look at your back, look at the things stand in front of you and shoot your bolt to strike while the iron is hot. That is the necessary thing you must do after the failure.
