Everyone in the world want to succeed. In fact, an opportunity comes every once in a while. On most
of occasions, it appears without noticed. Only when the opportunity has left us do we realize that we have
lost one. Some people know the importance of opportunities. They know an opportunity is factor in
achieving success. But they are always ready for an opportunity when it arrives. However, other people
give in the efforts to seek opportunities and grasp them. They are used to wait for opportunities knocking
on our doors. Most people are given opportunities, but only the more intelligently and hardworking people seize them.
