Opportunities don't come often. They come every once in a while. Very often, they come quietly and go by without being noticed. Therefore ,it is advisable that you should value and treat them with care. When an opportunity comes, it brings a promise but never realizes it on its own. If you want to achieve something or intend to fulfill one of your ambitious, you must work hard, make efforts and get prepared. Otherwise, you will take no advantage of opportunities when they come to visit you. The difference between a man who succeeds and one who does not lies only in the way each treats opportunities. The successful person always makes adequate preparations to meet opportunities as they duly arrive. The unsuccessful person, on the other hand, works little and just waits to see them pass by.
