There are two types of motivation: intrinsic and extrinsic. Intrinsic motivation is by far the better of the two because it motivates people to achieve goals from within themselves, not because of a prize they want or a punishment they want to avoid. After years of study on the subject, scientists could still not find a way to enhance intrinsic motivation in people. Intrinsic motivation not only makes people perform well and more accurately, but the people do not expect anything for doing it- the activity in itself is the reward.

Extrinsic motivation is getting more common in the modern society, using bribes and threats as weapons for getting things done. Volunteer services are scarce and more people expect higher salaries because of greed. Unlike intrinsic motivation, which comes from inside, extrinsic motivation is created from external factors. Extrinsic motivation, whether it be in the form of threats or bribes, do not work as well as intrinsic, but they get the job done, which is why most people use extrinsic strategies in life. Because so many people use extrinsic motivation as the way around intrinsic, people have grown to used to and expect answers involving extrinsic factors when asked to perform tasks.

When people today are faced with assignments, they usually wonder one or both of the following questions: "What do I get if I do it?" or "What happens if I don't do it?" These are both types of extrinsic motivation- normally a person never volunteers to do the assignment as a random act of kindness, but of greed or fear. Most people assume that extrinsic motivation is the only way to get things done, but they are far from correct. In fact, studies show that over both a short and long period of time, a task that is intrinsically motivated gets it done much more accurately and efficiently than if the same task is extrinsically motivated. Although intrinsic motivation works much better, it is a lot harder to use because it often discourages people, leading them to be lazy or unconfident. On the other hand, most people face extrinsic motivation with loopholes to the guidelines of the task- they want to do the least amount of work possible and still achieve their goal- whether it be gaining a reward or avoiding a threat.
