A writer becomes unique when he has a wealth of original ideas and he can write about these ideas in a very engaging creative style that keeps a reader's interest focused on his work.
Originality means the written work came from the writer's own thoughts and ideas. He may have researched some facts and information on a particular topic, and use these as references and quotes, but putting them together in a comprehensive and readable poem or prose still requires a lot of brain work.
Creativity on the other hand involves a lot more as it requires the writer to put together his ideas in an interesting style, and if it is poetry, he may need to present it in a very attractive, strong, or persuasive style and form.
Writing becomes completely rewarding when read if these two aspects combine. Writers who are diligently gathering ideas for their work are very receptive to things around them like the beauty of nature, human struggles, the pressing issues of life like love, courage, pain, loss, triumph and the
mysteries of the after life.
Writing is continuous learning, as life is a never-ending acquisition of knowledge and experience. Those who will not seriously consider this will
opt to just "copy" other writer's ideas
preferring the easy way to the craft, we call it "plagiarism" - stealing
the work of other writers.
Plagiarism, even just the stealing of a title to a work, is pathetic. It shows the person cannot produce anything from his own thoughts, he has no originality.
He is not able to express himself using the richness of the English language and so he "steals" for a quick poem or prose to post. In the end, he is just fooling himself, and living a life of pretense as a "writer".
Like all other skills, writing is a craft that needs to be honed and nurtured. It is a passion that grows better with use, and it gets more rewarding through the years. Real writers devoted to their passion become
artists with their pen. That is the result of using originality and creativity very well, when writing becomes an art.
