I don't really know where to begin with this paragraph. My instructions are to type and revise the following paragraphs so that they’re easy to read as a presentation. Use simple sentence structure. Use correct placement of old and new information.

Human motivation is challenging to inspire and quantify. Psychologists, teachers and business leaders have developed innumerable theories to help define and encourage motivation. However, careful study of motivation eventually dictates learning about goal-setting.

Goal-setting is a reliable motivator. Having a goal usually leads to better performance than not having a goal, even if you don’t achieve your original goal.

An exception to the effectiveness of goal-setting is when the goal is not feasible. For example, if you’re a middle-aged person with no exercise history, setting yourself the goal of running a 10-kilometer race in a year is an achievable goal. In contrast, the goal of running a marathon in a year is less achievable—and may be dangerous. In the workplace, extremely high goals cause people to cease to cooperate with coworkers or cause overall job performance to suffer.

Commitment improves the likelihood that you will achieve your goals. Two factors influence your level of commitment. External pressure is embodied in an authority figure. A peer group can also be an authority figure. The authority figure encourages or threatens you if you don’t achieve. Internal pressure includes your expectation of success and rewards you give yourself along the way.

The paragraph doesn't make sense to me. Therefore, I'm having a really hard time "paraphrasing" it. Here's how I rearranged it. Please tell me if I'm doing it wrong. Thanks so much!
