James 1:19,20

So then, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath; for the wrath of man does not produce the righteousness of God.

When we slow ourselves down on the pathway to getting angry, we have more time to gain control and think things through. Getting angry can be a buildup of many things until we just explode. If we learn to slow the process down and deal with the original problem that upset us, it may not have to lead to anger. We must always consider whether the anger is worth losing our righteousness over.
