In 500 words or less? This should be an interesting experiment. As a writer, (a person who makes their essential living from the "craft") I look forward to the completion of this exercise to be precisely 500 words without using clever little tricks and foibles though I will experiment with concepts of grammatical importance or non-importance as the case may be while continuing on in my quest for perfection. This is, as Musashi says, impossible to attain. (Check out my Book of Five Rings!)
What exactly is it that a writer does? Better, what is a writer? And what the hell is the difference between being a writer and being an author. And don't come back to me with intellectualisms about the variance in definition. Are we talking about a word mechanic, a passionate artist, a hack that writes specifically to sell? Someone who believes they have no choice but to perambulate within the structure of the governing language?
I am a writer...period. I craft concepts in novels, non-fic, poetry, whatever I am driven by my own needs to create and I always acknowledge a higher source of intelligence than I can ever be that is in charge of getting the damned things written through the quick facility of my fingers. With the help and aggravation of my personal editor who constantly breaks my chops about this and that relative to the "art," I am able to actually get things done. I won't even discuss the fights we get into because of her incessant not understanding my profound mentality and wit and wisdom that she instantly cracks through and makes me laugh about.
I'm a writer. Most of my stuff is brilliant. It has to be in my estimation otherwise why would I take the responsibility upon myself to perpetrate my own fantasies in fiction and why would I not think I am the greatest teacher that ever wrote a non-fic piece? At the same time I have to know when my stuff is full-blown blah. The differentiation between the two is something that I have come to terms with in my "writing" life and I sincerely enjoy tossing the garbage. On the other hand I get intense when I have to rewrite and restructure what I know is destined (in my mind) to be a commercial success though that is not why I practice the "craft."
Writing novels puts me into the persona of every character that appears in the work. That is a kick in itself especially when I am the female on the receiving end of male impertinence or a thorough blackguard that I despise. Nonetheless they are all aspects of my inner being as an artist and "writer." Non-fic, on the other hand insists I represent myself as the true master of what it is that I am attempting to get across to my students and readers.
I'm a writer; lucky me. You have a day job? Lucky you! 500. Bingo!
