If you control your anger or possibly a better wording would be if you understand your anger and except your anger it is a good thing and there is a lot of energy there to be used. If you do not understand your anger or if it controls you it is a bad thing.
And I know from experience the suppressing your anger is a very very bad thing it will eventually come out, you can only suppress it so long, and when it does come out you are now looking at rage full on mindless rage.
I think this is an important lesson for marriages too. My wife and I decided a long time ago that we would rather have an uncomfortable conversation than a long list of things we can't talk about. Sometimes it's hard, but we always confront the challenges in our relationship.
It can be painful. For a moment, the person you know the most in the world suddenly seems so far away. The only person who really understands you and accepts you is now on the other side of a wide gulf. But you have to make the effort to bridge that gap, and when you do the two of you are closer than you ever were before. We've never yelled at each other, never fought. We've had some very difficult discussions and had to confront the things we've done that have been wrong or hurtful, but we've never hurt each other on purpose. And when we try not to have that difficult discussion now, the other person knows something is wrong. And the longer we go before being honest with each other, the more painful and difficult it is when we finally are.
It will always come out. If you're going to spend eighty years with someone, she'll eventually know every bad habit or embarrassing attribute you try to hide from the world. It doesn't do any good to suppress your frustration or try to swallow your anger. You have to be honest and open with that person, and she has to be that for you. And if you are, you will have a far more rewarding relationship than you could ever have imagined.
Sure, sometimes I get angry with something she does, and sometimes something I do upsets her. But we both know the other person would never upset us on purpose, and now we can safely discuss those instances of frustration in a healthy way without being afraid that the other person will react badly or leave. Because we recognize, accept, and own our emotions. And the role we
both play in the way those emotions manifest.
Anger comes from self preservation. It is an evolutionary self defense mechanism. When people tell you that being angry is evil or wrong or makes you weak they are denying an inherent part of the human experience. Anger isn't good or evil. It just is. What we do with it once it manifests is what is important.
