Happiness is Doing What You Love. or Oh My Gods, What Have I Done?

I have a brother who is a Captain and Tennille fan. He is also a bigwig. By that I mean he was recently chosen to be the president to a 30 million dollar a year privately owned company, and one of the two hardest workers I have ever met. The second is my wife. Lorelle busts her ass harder than Tyler does.
Anyway, after reading my last post Tyler sent me a text saying, "How come I'm president of a 30m company and you seem happier than me? You little pud."
My response was, "You just answered your own question. This morning I woke up, made some coffee, picked some cherries, played a round of disc golf, then went home to write a space battle. Your day was slightly more stressful I would guess." As a side note, Lorelle encourages me to play disc golf with a friend twice a week because it gets me off my butt. I love my wife.
My blood pressure spikes just like my brother's does, but in my case it is because my new Star Mamba driver lands in the creek, or maybe supper is later than I'm used to. Seriously, Lorelle will tell you, a me without food is an agitated me. A very agitated me. That's the Happiness is doing what you love part of this post.
But the Oh my gods, what have I done? part exists, too. That same night, just twenty-four hours after I officially quit my old job, book sales hit a thirty-day low. Before I went to bed that night, I looked at my sales. After using my home defibrillator on myself, which entails taping two bare wires to my chest and plugging them into an wall outlet, I swallowed a shot of whiskey and tried to sleep. Slumber did not come easy.
The next morning I woke up, made my coffee, had some fruit for breakfast, and opened my Chromebook. After reading the news and tabbing the science news I needed to read, I clicked on the tab for book sales. All was right in the world again. My sales for the first eight hours of the day were just a little higher than my entire sales day reflected the day before.
The obsessive-compulsive side of my personality, which to Lorelle's chagrin does not bleed over into cleanliness, compels me to analyze things like this. How does one Saturday compare to another? Do sales jump on common paydays? If the Moon is rising in Virgo, do sales dip? You get the idea. But this dip and jump coincided with nothing I could measure. No solar flares, no double rainbows, not even the arena vote in Sacramento. There was no discernible connection between the calamitous drop and sudden rise in daily sales. That frustrates me. It fell into the category of Why the hell can't I figure this out?
In my previous business, I faced the same sort of thing, but it was on a much larger scale. To some degree though, I could predict what was going to happen in my work, based on what was happening in Lorelle's, since the two industries were related. When she had a slow spell, I would have a slow spell about four weeks later. When her work picked up, mine would about four weeks later. As a writer, I no longer have that barometer. That adds to the What have I done? sentiment.
The point of this is one that will benefit writers. The rest of you have read my ramblings for nothing other than a glimpse into my world. But for you writers out there, I've learned something. Look at your sales every day if you want to, that's fine. But DO NOT stress over a low day, because there will be others that balance it out. In fact, just look at your thirty-day averages, which is something that Amazon's KDP program makes very easy with their new layout. That line graph is awesome.
Okay, now it is time to kill a few aliens while Judge Judy screams at stupid people in the background. I wonder if there is a correlation between the mentality of her litigants and the bloodshed in my stories.
