When all is said and done, I don't really think of myself as a writer (even though I've earned income from writing (off and on) since I was expecting my twenty-eight-year-old daughter). I'm a person who enjoys writing (and there's a difference).
I love writing. I'm a "words person". Inspired, I guess, by talk of the Founding Fathers and people of that time in history, I grew up (just outside of Boston) in awe of the power of the written word. Less "deep" than that, I love playing with words and the order and system of knowing how to put the right words together in the hopes of creating something for a reader. I love the clicking of the keys as I write. When I write I feel really happy, and if "happy" isn't the right word then I guess I'd say I feel "engaged in something that feels very right to me".
For me, there's a gap, though, between the fact that I really love to write (which is one thing) and the fact that I want to use the skill to write something worthwhile in this world. One wouldn't think that the element of writing and earning money for it (which, again, I do and have done for ages now) would be sitting there in that "gap" I mentioned, but it is. For me, it's as if the enjoyment of writing and the wish to (over-used as this term is) "make a difference" in people's lives are both separate and yet (needless to say, I guess) connected.
The earning-income element (while a nice way to earn income and certainly better than SOME work) pretty much means nothing to me (or at least to "my heart and mind").
I write because I think everyone should write. It's a form of communication; and after a few decades of living as an adult, I'm very bothered by how much unnecessary misunderstanding there is between people (and often uncalled for hostility as a result). Between living x number of years and having x number of experiences, I've come to understand things that I never understood before either; and I hate to see what I've learned "the hard way" be wasted by my not writing. It's not just what we've learned along the way, though. It's also about why we do some things.
Our society/world has become so technology-centric since, say, around the late sixties/early seventies; it's as if the power of words and the importance of real communication have been forgotten. The real reason I write (when I write what I want to) is that I think everyone really should write and communicate. We can all at least TRY to improve things.
