'Never go to bed angry'

While it is true that issues and emotions should be addressed and dealt with appropriately, it is never healthy to suppress emotions, which is what you are essentially doing by trying to impose a time limit on them. Anger, like most other emotions, is in and of itself healthy. It serves to prepare you to respond to somebody that is potentially violating you. Problems with anger arise in its expression and regulation. Anger needs to run its course so that it doesn't fester and grow into something much greater with time, like jealousy or resentment. This isn't to say that it should be left alone completely - it should be dealt with in due time. This 'due time' will vary between people but you should know when your own time comes.

Now let's address my premise that the problems with anger arise in its expression and regulation. Never in my experience has a relationship broken down because of one person being angry at the other. Rather, people say things they don't mean, or they fail to address the issue appropriately and thus let it become something worse. First of all, be aware of your emotions. Acknowledge that you are angry and why you are angry. Unregulated anger often comes with the feeling or belief that the object of your anger has purposely provoked it, so the first step is to do all you can to eliminate this idea. Do not try and resolve your anger by attacking the other person. The aim is not to level them or take revenge on them, it is to reach a workable resolution that satisfies both parties and creates a greater understanding.

As has been said elsewhere by others who are older, wiser, and better written than I (Robert Greene, to be specific, and you can find him on http://www.powerseductionandwar.com/), if it was honourability that was at the root of human nature, then an argument would be an attempt to discern the truth, in which each party to the argument is ready to totally discard his or her ideas or subscribe to the ideas of his or her opponent. Unfortunately, baseness is at the root of human nature, and most people would rather take their own ideas over the truth. Keep this paragraph in mind next time you are arguing or angry.

Another misconception that I will take this opportunity to address is the idea that fighting is bad or undesirable. Fighting, contrary to what many people think, shows good communication. I would much rather a partner blew a gasket and screamed at me for half an hour the first time that I did something that made her angry, than withold from me her anger and end up killing my housepets and sleeping with my best friend or something. Or killing my best friend and sleeping with my housepets, whatever. It's true that some fights should be walked away from and not bothered with, and if you are fighting over trivial crap like whose turn it is to buy condoms, then you may have a problem. You may also have a problem if every fight of yours entails breaking up, each of you sleeping with 3 people and slandering the other on facebook then meekly discussing it more calmly, reaching a simple resolution and getting back together.
