A、Because it will make a person earn a lot of money. B、Because many people in the world don’t want to be square pegs. C、Because

Sometimes we say that someone we know is "a square peg in a round hole". This simply means that the person we are talking about is not suited for the job he is doing. He may be a bookkeeper who really wants to be an actor or a mechanic who likes cooking. Unfortunately, many people in the world are "square pegs", they are not doing the kind of work they should be doing, for one reason or another. As a result they probably are not doing a very good job and certainly they are not happy.
    Choosing the right career is very important. Most of us spend a great part of our lives at our jobs. For that reason we should try to find out what our talents are and how we can use them. We can do this through aptitude tests, interviews with specialists, and study of books in our field of interest.
    There are many careers open to each of us. Perhaps we like science, then we might prepare ourselves to be chemists, physicists, or biologists. Maybe our interests take us into the business world and such work as accounting, personnel management or public relations. Many persons find their place in government service. Teaching, newspaper work, medicine, engineering—these and many other fields offer fascinating careers to persons with talent and training.
