I'm inclined to think writers write, be it creatively, technically, academically, socially, or whatever. When one is able to string otherwise abstract glyphs into a meaningful and shareable narrative, it's writing and it's a writer who does it.
For most writers, the need and ability emerges in kindergarten or soon thereafter. Whenever I see or hear someone who's written or said "aspiring writer," I die a little. Aspiring to be able to communicate in writing? I have a three-year-old nephew who's an aspiring writer. Just hand him a crayon and he goes at it.
Author isn't much different in meaning from writer, dennotatively. Poet or another language equivalent was the term for a creative writer regardless of genre prior to the Fourteenth century. Because of English language words' tendency toward second syllable stress, writing and speaking it tends to be in iambic rhythm, a short syllable followed by a long syllable, as in the word wri t-e-r. Trochee is the opposite of iambus, pronouncing a stressed--long--syllable followed by an unstressed--short--syllable, as in D-i-d it, and has a more rapid and rolling gait than iambus. All prose is poetry when it's perceived as such.
The thread topic question is mostly in iambus, a line of heptameter with an additional, changeup stressed syllable, fifteen syllables in short-unstressed, long-stressed sequence. When S-h-o-u-l-d you F-e-e-l Com f-o-r ta b-l-e Call i-n-g Your s-e-l-f a Wri t-e-r. The particle "a" affects the rhythm, following the stressed "self" with a stressed syllable. To be frank, only for illustrative purposes, I feel the impact of the question is blunted by the particle. //When Should You Feel Comfortable Calling Yourself WRITER?//
In my view of the cosmos, we creative writers are poets. I've been a writer since nursery school, poet not long thereafter, and published-in-class author as soon in time. My calling card with my phone number and public e-mail address reads, Starving Poet, Artisan, Woodcrafter. When someone asks me what I do for a living, and it's not the most polite question to ask, I answer, Work. An emotionally interesting and interested interlocutor would ask, What are your passions? Then I answer, Reading, appreciating beauty, creating art. If the conversation goes on from there, something more meaningful might develop.
Spread the love of written word.
