Great questions, Dr.
Yes, ethics for writers can work for each individual based on their values and culture. What works for one writer may not work for others.
Yes, all writers need self-discipline, which may sometimes be difficult in creative writing. Self-discipline helps writers know where to draw the line and when to take a break. When not to talk loud on the phone.
I work hard as a writer to put a break on my imagination and thoughts. Also, I firmly remind myself as a creative writer; I have an obligation to write what many people think or feel. Sometimes, I crossed the line and wrote what many people were thinking or too scared to write.
Yes, as writers, we need to respect ourselves and others. Share our point of view and permit others to share their and, importantly, learn from others and support one another.
