There are certain goals you want to meet. There are specific requirements you have to meet to attain such goals. Those requirements are called sacrifices. In order to make those sacrifices, you need to restrain yourself from certain things in order to meet those requirements. Meeting up with those requirements will take you to your desired goal. This is what is called self-control or temperance.
For example, you want to eat healthy. There are certain foods you are supposed to cut back on in order live healthy.
In order to get to that place of satisfaction, you need to sacrifice, restrain yourself, control yourself for the greater good.
