Motivation is an internal impulse that brings us to complete an action. Without motivation, there is no action.
Motivation is important because it is what causes us to actively look for resources to guarantee our success. While some motivation requires a conscious effort, others, like looking for food, eating, and finding a sexual partner are innate motives that we are born with and allow us to stay alive. Secondary motives keep us motivated to do activities and learn, which depend on each person’s culture.
Anyone who has struggled through the dreaded History, Chemistry, Math, or English class knows that not everyone is motivated to learn the same things. You might find that sitting through English class was a breeze, but your classmate struggled to read all of the books in time for the exam. Maybe you can learn a recipe with ease, or maybe you learned how to build an engine on your own. These kinds of tasks show your motivation to learn and can highlight an important part of your learning process.
Motivation may come from your own interest, or it may come out of necessity (having to learn something for work or survival, like changing a car tire).
