Are you talking about being angry?
Man, did I used to have a temper. I would be out of control. I realized that when I was angry at someone or something, it was because something was wrong and I didn't like it. So I would get angry and use my anger/energy to fix the problem or control the problem. But I made more problems as I released too much energy/anger and I would lose control of myself.

There is a short moment when you realize you are feeling anger or energy and that's your chance to tell yourself to stop. You now have two options. First option is to forget what's wrong, let it roll off you. Deal with it later and only deal with it as slow as possible so that the object or person knows you are in control. Walk slow, talk slow, do everything slowly.

The second option is right after you feel the anger/energy building up is to again think the word stop. But this time when you think stop, you take a step back in your mind and look at the situation from the other person's shoes. Then look at the situation from your point of view again. And the last thing to do is look at the situation as if someone else was watching the whole thing. Now, you take control of the situation with your words only and make a compromise or work out a deal. Talking just slightly slower than normal helps. Asking questions also helps.
