"Writing, I think, is not apart from living. Writing is a kind of double living. The writer experiences everything twice. Once in reality and once in that mirror which waits always before or behind."
When looking to "fortify" your writing, always go after two goals: precision and energy. The more precise your language, the less-cumbersome your writing reads, allowing you to express ideas with just the right amount of words.
Creative writing is considered to be any writing, fiction, poetry, or non-fiction, that goes outside the bounds of normal professional, journalistic, academic, and technical forms of literature.
