I agree that some persons give up in the beginning of the work. They are lacking in self confidence or required resources or any other reason due to which they give up quite easily. Some people are courageous to take every challenge. They don't hesitate to take initiatives but due to any reason they give up in the middle. But some people keep on moving towards their goal and eventually they succeed. But it doesn't mean that those who leave their efforts either in the beginning or in the middle they are not worthy enough. It might be possible that they may succeed in any other activity wherein they have good hand.
