There is an old proverb that says: "Before doing any act, ask yourself two questions:
(1) What will my mother think if she knows I am doing this? and,
(2) How will I feel if my action were to be published in tomorrow's newspaper?"

It is essential that you choose a career that will not only bring you success and money, but one that will give you the pride and satisfaction of having done something worthwhile with your life. Many people take up particular careers and then realise that even though they are making reasonable money, they are being forced to bend their morals, compromise on their ethics, and do acts that bring down their own self-esteem.

When you are at the stage of choosing your career, the whole world is open to you. Look around and talk to people who have been working since a number of years. Ask them whether they are proud of their work, and whether there is a meaning in what they do on a day-to-day basis. A recent survey conducted by Duke University in USA found that the largest number of students who admitted to cheating (56%) belonged to the management and business administration areas.

Similar surveys have revealed that journalists are finding it harder and harder to follow their conscience and value systems in their work, while geneticists are generally working with deep inner satisfaction since they are contributing towards better health and longer life.

You know (or rather, you SHOULD know) what your strengths and weaknesses are. Match them to the career you are about to select. Ask yourself whether you will be able to work for the next 40 to 50 years with a clear conscience, and with the sense of satisfaction that not only are you earning well, but are also serving a greater purpose in society. 

If you set such a goal, you will find your interest in studies increasing, your results improving, and your progress becoming much faster – and you will never face stress in your work-life.
