After you have dealt with an issue, let it go and move on.  Do not keep a long record of wrongs.  That will on ly make your situation worse. If you hold on to grudges from the past it will make your fuse shorter.

People who are quick to forgive have fewer anger problems than those who hold on to the problems.  If you can reconcile past relationships it also decreases the chance you will get angry.  This may take some extra work, but you need to learn to forgive.  If you don’t then grudges will continually burn your fuse.
