Attitudes and values are shaped over time when a person matures. These are highly influenced by external factors like family, friends, and environment. They are highly affected by experience and varies from person to person. Often attitudes and values are a result of consequences of the actions that an individual takes in the course of his life. If a person grows in an environment where growth and restriction are common, it often leads to negative attitudes and values. A person's environment is probably the biggest factor in molding character and should be highly taken into consideration.
