Values are vague, global concepts, sometimes difficult to understand.
A value is something that is important to you or that you feel has worth such as marriage, family, religion, education, etc. What has little value for one person may be of great value to another. Values tend to permeate and influence all aspects of our lives. Just as life is ever changing, so are values. Values evolve and continue to develop just as the individual grows and develops.
