To be human is to be angry some of the time. Anger, like a hammer, can be a tool for destruction, or to build something. We can turn it inward and beat ourselves up. We can use it to correct a situation that is wrong. All social movements had their beginning in some one feeling angry.
Anger is a powerful tool for social change on a personal and social level.
We can use our anger as a tool for change. When we use anger in a positive way, self-esteem increases. Anger is a coping mechanism for dealing with some event that threatens our body, property, self-esteem, values of what we hold dear, or when we don't get our way. Therefore, you are the only one who can make yourself angry. You choose how you respond to events that upset you.
