What's the most important thing to influence your mood?

Had a very bad month. Not the worst one ever, but bad enough to hit me hard. So, I did my very best to handle it the right way. My wife told me that I was unrecognizable during that period. That hurt my feelings. Salary or income or clients aren't the things to determine my mood. I mean not the most important factors. Yet, my wife wasn't convinced. So, I asked, couldn't I say the same for her, when she had a bad day at work. She said no. There are other things she definitely cares more about. I realized that I crossed the line. She obviously cares about our kids' well-being the most. On the other hand, this was an obvious sign that my work success or failure can lighten me up or hit me pretty hard. If this wasn't true, then I would say, this isn't right, the end of story. But, the obvious thing that I become so emotional about it speaks for itself, doesn't it?

When my business runs smoothly more or less, I'm not in a perfect mood, but I definitely worry less. So, you can say that this is a positive mood. I can also be quite enthusiastic if I find a great client and match my projected income expectations. Guess, it's stronger than me. Do I have the right to feel helpless about it? Is there a way to keep our mood intact or protected, under some kind of an emotional shield all the time, so no outside influence can shake it in the wrong direction? Or maybe you have to admit yourself that there are things that can be described as your mood shakers. You make a list. You figure out which ones are the strongest and you create the proper defense mechanism or something. It would be interesting to hear what are the things that can throw other people off balance for a short or long period of time. Are you just like me in the business zone that influences your mood the most? Or maybe you have other positive or negative mood triggers, like your health situation, for example. Let me hear you.
