Hi, Steve. This piece resonated with me a lot. You got me from the very first paragraph because I was also the kind of person who started a lot of things but not finishing them. But I guess we all start somewhere, right? I believe the pain of discipline is, at least, better than the pain of regret :)
There are many useful resources and platforms to thrive as a writer, and they are mostly free. As long as you believe you can, then I also believe you will!
I enjoyed reading this story. You'll be amazing at writing, I can see that! Happy writing and best wishes to your writing journey! :)
