Answer:
We often hear people say that opportunity knocks only once. But I truly believe that opportunity will not knock until you build a door.
What is the meaning of building your door? It means preparing yourself and working hard to develop your skills and talents. To be ready to take opportunities when they come your way.
Opportunities are everywhere, but you may not always spot them immediately. They will come disguised as challenges, problems, and obstacles. But if we have built our door, if we are prepared and ready, we can recognize these problems, and make the most of them.
Build your door, and the opportunities will come. Work hard, prepare, and be ready to seize the opportunities that come your way.
