In my opinion you write well, precisely because of the approach you outline in this article.

I certainly do not relax enough & bring myself down because I constantly feel that I have written poorly.

Yes, I write with passion from within but I am also of dour British origins and schooled (perhaps overly so) in grammar, spelling, nuance and an appropriate choice of words. Whilst this can certainly be of benefit, it can as easily get in the way of flow and even, at times, the connection to audience that you suggest the importance of which you learned from Art Bram.

I have also found that writing well can actually interfere and sometimes even destroy connection with audience. That happens, in my view, and paradoxically, because as literacy has increased, so has written communication become more common and and eloquence, as opposed to messaging, has suffered. In addition, the vernacular and colloquialisms have become increasingly common and seen as acceptable.

The advent of the digital age & social media has increased this tendency such that, for many, well constructed, grammatically correct prose, well constructed sentences, carefully chosen vocabulary and appropriate punctuation, often become an obstacle and are often seen by many as reflecting a pompous or pretentious character.

I am very much in favour of inclusivity and have no doubt that, to paraphrase, wisdom can come out of the mouths of babes, or those lacking in schooling or sophistication. However, when standards fall such that care, thought, nuance and meaning are lost or potentially distorted, my view is that more harm than good is achieved and the best of intentions can go awry.

So, yes I agree that writing ought to be enjoyable and authentic and accept that it is better to be heard inadequately, as long as one's message is understood. At the same time, I fear that real treasures can be lost in the morass of mundanity, endless repetition, false logic and disastrous technique now so commonly present now even in the work of those for whom writing is an occupation, such as professional authors and journalists.
