I have started writing not too long ago. The main reason why I started was just to have fun and relax. I've read a lot of stories here and on other platforms and I said why not?
As I went through the first few chapters I realized how much joy it brings me and how fulfilling it feels for me to actually create something that I call my own. I don't get many readers or many collections but I did get a contract for it. To be fair, I didn't know much about contracts and I was just relieved thinking that my book has been at least liked enough to get the contract. But then I read some things about contracts and realized it's not that big of a deal as I initially thought. But again, the recognition for me would be just a bonus since I am already having a lot of fun writing.
Honestly, I already planned most of the ideas that I want to incorporate into my book. However, I plan to write quite a lot, and so far, I have already changed quite a few of the initial ideas for the book. By the time I reach the actual milestones that I have set up for the book, lots of things might have changed already, from the plot to even the idea itself. And so, at this point, sometimes I even "forget" it's my work and I am just excited to see how it will continue, because until I have hit that publish button for a chapter, I might change it a hundred times. I know what the next chapter for my book will be about, but I am eager to see how that will be written.
Regarding having a few readers, well, I feel like usually the more diverse your book is, the higher the chances of someone finding something they don't like and dropping it are. It also means that they will surely find something they like, but it will balance the things they don't and in the end, they might not even put it in their library much less vote for it. But that's fine! After all, it all depends on what you are writing for. If you are writing for money and you try to have a very big audience, then yeah, it might be frustrating. But if you are writing just because you really enjoy it and do not care as much about having many readers, then even one regular reader is enough.
Just knowing that someone else really enjoys my ideas and writing is usually enough for me to continue writing.
