Good Writing

What makes writing... good? 
Is it the feelings it provokes... the flashy fantastic words used... the skillful grammar... the thoughts it brings up... the masterful crafting of a story... the unique characters and their journeys... the interest it brings upon... the universal tone... or the singular original voice... 
???
Maybe all of the above are what makes writing GOOD.
But when one writes every day, that GOOD of a writing is very hard to achieve on a daily basis. Not impossible to achieve, but very hard nonetheless. 
Mostly I walk out of my daily writing routine happy I stood by it and stayed on track. And mostly -  shrugging my shoulders because I found my writing for the day just OKAY or even PREETY BAD, or MEDIOCRE to say it kindly.
Still, the challenge of writing isn't to write well, or GOOD as I like to whimsically say, but it is simply to write. To communicate. To share. To express. To find. To explore. 
Making writing a subjective result geared art form diminishes all that it can be beyond the GOOD that it can be. 
So in short, don't try to write something GOOD. Just write something.
