The writing life is different for everyone who’s a writer–and that includes everyone who has written something, published or unpublished, or considers they are a writer because of whatever reason. (Some unpublished works are better than published).
Sometimes, experience in a field or industry counts in writing about that field of industry. Sometimes, a writer takes the bull by the horns and just writes.
Whatever way, acceptances and rejections come one’s way no matter how the writing is and what it’s about, no matter how noble or realistic and so on.
Through it all, a writer never gives up on writing, which is a writer’s default setting.
