I was recently reading about the power of our personal decisions and how even the smallest choice we make can change the course of our lives.
For example, a person bought a new pair of shoes and wore them to work in a bar. Halfway through the night, one of the soles came loose. This prevented him from going out with his friends after the bar closed. He could have, but he figured he’d rather not deal with the damaged shoe the rest of the night. He instead went home, went online, and met a young woman in a chat room. Two years later they were married and having their first child.
So if his shoe hadn’t fallen apart and made him decide to go home instead of out partying, he never would have met his future wife.
I read another example about a guy whose best friend was about to move across the country for a new job. The night before his friend left, they went out and got drunk, then later the guy decided to buy a one-way airline ticket and join his buddy. The job ended up not working out, so the friend returned home, but the other guy decided to stay in the new city. Seven years later he was married, had two kids, and a great job.
Again, a simple, spur-of-the-moment decision changed his life forever. 
It blows my mind when I sit back and consider all the decisions I make on any given day. I decide what to eat for breakfast, what clothes to wear, whether or not I need to shave, what route I drive to work, what I’m going to have for lunch. The decisions are constant and never ending. And each and every one of them changes the course of my day, and potentially my life.
Using myself as an example, when I first moved to Tallahassee I met a guy at a restaurant where I had recently gotten a job. He invited me back to his apartment complex to hang out and meet some people. One of those people was a young woman. She and I would run into each other on and off over the next seven years, until finally one day I asked her out. We’ve now been married for twenty-seven years.
So if I had turned down the offer to go to this apartment complex and meet these people, I probably never would have met my future wife. Amazing, isn’t it?
There’s a theory in theoretical physics that suggests every decision we make creates a new timeline or a new universe. Every single one. That’s an idea that keeps me awake at night considering the possibilities and wondering how my life would be different if I had worn a green shirt today instead of black, or if I’d smiled at that person I passed on the sidewalk instead of staring at my phone screen.
That’s one of the things I think about when working on a piece of fiction. There are so many possibilities to consider – although I try not to overthink when writing fiction, otherwise I may end up in the weeds. 
But still, as I’m writing I’m making decisions with each sentence, even every word, that I type on the page. With my writing style, which is akin to absolute and unplanned chaos, I really don’t know where my stories are going to end up. I usually have an idea of where I want it to go, but the protagonist, or maybe a supporting character, will more than likely make an unforeseen decision and the story takes a left turn into unchartered and unconsidered territory.
Not that it’s a bad thing. I love the unexpected in fiction. I think that makes it more like reality, like life in general. We get up in the morning with plans for the day, but how often does it all work out the way you expect it to?
And from a writing standpoint, I like it when my characters take the lead and show me things I hadn’t thought about or considered. As the saying goes, “No surprises for the writer, no surprises for the reader.”
