What does " the final behaviors" mean? could you explain it to me?
One outcome of motivation is behavior that takes considerable effort. For example, if you are motivated to buy a good car, you will research vehicles online, look at ads, visit dealerships, and so on. Likewise, if you are motivated to lose weight, you will buy lowfat foods, eat smaller portions, and exercise. Motivation not only drives the final behaviors that bring a goal closer but also creates willingness to expend time and energy on preparatory behaviors. Thus, someone motivated to buy a new smartphone may earn extra money for it, drive through a storm to reach the store, and then wait in line to buy it.
