Opportunity is one of the elements of success. But opportunities dont come often. And not all the opportunities can certainly lead to success. Moreover, opportunities are usually disguised as hard work; therefore most people dont recognize them. So if you want to achieve something, you must make efforts and get prepared. Otherwise, you will take no advantage of opportunities when they come to you. In my opinion, there are plenty of opportunities for everyone in our society, but only those who have made enough preparations and are highly talented can make use of them to achieve their purpose.
