Newton’s Third Law of Motion — Physics

Newton’s third law of motion states that for every action, there’s an equal and opposite reaction. This is how swimming works. The swimmer kicks the water and the water pushes the swimmer up.

Yet, I believe that Newton’s Third Law is a universal principle as much as a physical one.

In psychology, this is called the principle of reciprocity. If I do someone a favor that person may feel obliged to return a favor sometime in the future.

You get out what you put in”, is a popular saying. I can speak from experience that this is especially true for extracurricular activities. They are voluntary by nature thus it’s up to you how much work you want to put in. There’s much that can be gained and it’s only through putting in the work that you can receive the benefits.
