Motivation can come from three sources, two of them external and one internal. However, motivational sources differ in degree of effectiveness. Indeed, two of them can occasionally lead to negative outcomes.
    The first end least effective form of motivation is typically characterized by some kind of threat. There is often a fear of some unpleasant consequence. For example, "If you don’t study hard, you’ll fail your exam" or "If you don’t finish your work on time, I’ll have to fire you." People usually respond to threats of this kind, but they are likely to carry out their tasks with little enthusiasm and with minimum effort.
    The second form of motivation comes from a pressure or desire to please. You may be afraid of disappointing people you want to make happy. Students often study very hard in order to please their teachers and to achieve what their parents went for them. This kind of motivation also often works, but can sometimes be dangerous if what teachers and parents went is not the same as the student’s own desire end ambitious.
    Finally, there is the internal source of motivation, where the task is carried out because the individual is personally committed to it. With this kind of motivation, studying or working becomes a pleasure and not a duty. A wise man once said, "If a man finds a job he really loves, he will never work again in his life."
    In life we are driven by a combination of all three forms of motivation. They coexist in educational systems, affecting students, parents end teachers. However, in our pursuit of better more effective education, we should constantly be aware of the three forms. We should seek above all to make the greatest possible use of the third kind — the personal motivation of the individual.
