Many young children love to play make believe and use their imaginations. Some like to be more creative. A handful might like to make up concepts in their minds. I was definitely like that.
As a little kid, I would imagine fan fiction of my favorite movies and TV shows and dream of seeing them—unaware of copyright law then. I also imagined my own ideas of TV shows.
When I was around 7 years old, I read a book called “Morris Goes to School”, which was about an upright moose who went to school with children. It was cute for a small child.
That had inspired me to write my own version, but about an upright polar bear named Spike.
Later I evolved Spike into a child polar bear who also went to school with children. Not long after, I did a spinoff of one character and imagined a series about her living in a house in a jungle with talking animals as her friends.
At about 10, I abandoned the idea of that imaginary series. However, fast forward 6 years and the idea came back into my mind. I was so excited that I wrote it into a novel. Sadly, no one, except those I knew personally, found it appealing. So, once I was 18, I removed it from the market.
No matter how much you love and value something, it isn’t always going to please people, especially if you do little to no research on that idea. Few adults and older kids are interested in reviving their childhood imaginations. Fewer want to hear or know about it.
As you get older, you realize certain ideas make little to no sense or aren’t as good as you thought when you were younger. Hey, that’s growing up.
So, while other writers tell you to write down any idea you have for a story (which I totally agree with), unless you’re writing it just for yourself or maybe friends and family, be careful with trying to market that idea. You may have to do a lot of research. You’ll also have to study the writing craft if you haven’t started already. And the progress can take several years. I’m not exaggerating—it took me 7 years to develop my writing voice and be able to write great books. Not just good. Believe me, it’s not nearly as satisfying as it sounds. After a while, I took the less-than-great books off the market.
