Goodreads asked Paul Gallimore:

What’s your advice for aspiring writers?

Paul Gallimore Try it. Write ten or twenty pages and then set them aside for a week or so. Then see what you think of what you have written in a fresh light. If you are not actually embarrassed by what you have written then you can probably write.

If you decide to commit to a full book, I would advise reading up on plot theory if it's going to be a novel. You might save yourself a lot of pain that way.
