Some people in the writing industry say no. They believe you are born with the ability to write creatively. If a person does not have this birthright, they shouldn’t try writing that novel. I think this is ridiculous, highly snobbish, and arrogant.
Creative writing can be taught and at any age. If a person has the motivation and desire, they can learn to write creatively and maybe even get published. Learning to write creatively requires two steps.
First is to learn how to think creatively. Such as imagining a traffic stop on the way to work and an elephant walks over to ask for a ride. Creative thinking is about imagining something different within something routine. It could also be about thinking a “what if” situation such as what if extraterrestrials took over the military. Sometimes creativity can come by paying attention to people in a store and thinking about what kind of life they could be living.
At this point, some people are saying “easier said than done”, but they are listening to the “no” people in the writing industry. A person can learn to think creatively through practice and guidance. Most writing teachers and books do not explain this process or consider the impact of skipping this step.
A person can learn the first step while starting on the second, which is learning to write what is created so it can be shared with others.
In the beginning, it is probably best to write it all out. It may not make much sense, but practice at writing and learning the writing rules will eventually make the creativity readable. At least the writing teachers and books can help with this step.
I think not teaching how to be creative is why so many writers-to-be struggle with their writing. Teachers and authors assume the person already knows how to be creative.
So, self-teach yourself. Maybe keep a journal/diary. Tell your dog or cat or cow what you’re thinking. How about right now getting a pen and paper?
