The Hidden Danger in Writing.
When we write, (and especially if it is fiction), we are by definition connecting to our consciousness. The words that get written down are but expressions of this.
But if history is anything to go by; there are many instances where this process of mentally exploring and creating literature holds the potential for adversely exceeding our human capacity. There is almost a flirtation with the unknown which could have consequences.
Cases in point would include: Tolstoy, Hemingway, Edgar Allan Poe & Virginia Woolf, all of whom experienced what is termed "mental issues," these days. Mental breakdowns we are informed arise in many cases from an overload on the brain. It must be like a nightmare; where one is struggling to leave the dream behind and attain consciousness; except in the case now being considered, one is awake and escape is that more difficult.
One could of course write airy fairy romantic novels, full of young, clean cut Arthurian heroes with Oxbridge degrees, opposite swooning maidens with prominent cleavage that ride white stallions; and that might even sell these days in train station bookseller establishments.
But then, any writer worth his salt, wants more than* that.
Some have been mentally tough enough, (if that is the right expression),* to slay their internal demons. The novelist Grahame Greene for example,* was always wrestling with the concept of his faith, yet managed to both ride the whirlwind and direct the storm of this internal conflict into producing some damm good books.
The aspect of creativity I think exists in everyone to some degree. If it is writing and the act is enjoyable to yourself, then you are lucky. If greater recognition is required beyond W.H.Smiths in St Pancras Station, then the future is more problematic.
