Goal-setting theory refers to the effects of setting goals on subsequent performance. Researcher Edwin Locke found that individuals who set specific, difficult goals performed better than those who set general, easy goals. Locke proposed five basic principles of goal-setting: clarity, challenge, commitment, feedback, and task complexity.

Huh? What does that mean?

One of the most effective ways to stay motivated is to set goals for yourself. However, the type and quality of goals you set affects how well they will work.

Imagine you are 30 pounds overweight and want to drop some extra weight. When setting your goal, you have several options. You could say, “I want to lose weight within the next year. I will go on a diet to lose the weight.” This goal is pretty vague and poorly defined; you haven’t specified how much weight you want to lose or what concrete steps you will take to lose it.

Alternatively, you could say, “I want to lose two pounds a week for the next four months. I will exercise for at least 30 minutes, five days per week. I will also change my diet to include three servings of fruits and vegetables as well as whole-grain products. I will also limit myself to eating out just one day per week.” This goal is much more specific and includes actionable steps.

The simple act of setting an effective goal gives you a better chance of realizing that goal. In fact, listed below are several principles crucial to setting effective goals.
