Values are convictions or standards that help define what is right or wrong. They come from parents, friends, teachers and dictate how people look at the world and make decisions. Values are stable beliefs about what is good or bad. There are two types of values: terminal values which are goals people want to achieve, and instrumental values which are preferred ways of behaving to achieve goals, such as honesty or courage. Understanding a person's values helps explain their behavior. Different generations and cultures can have differing values.
