If you are indeed thinking of becoming a writer, think and weigh your choices. Do you really think the path of an author is truly for you? I’m not degrading what you think you want, but there are plenty of stories of writers having a rough start before the spotlight finds them. Many authors have difficulty finding publishers that will accept their stories, and even then you might have to go through several trials before you’re able to find a single book in the public.
Becoming a writer has its many opportunities, as doing what you love or creating literal art that many could enjoy. Note that you will have deadlines for books or publications, and depending on your success, your budget also. It’s a hard life as an author, but if your conviction of becoming one is true and whole, then absolutely nothing could deter you from your goal.
Just remember that rivers rarely turn around and go another path.
