I love you say, sometimes you just need to forget everything and hit publish. Sometimes your writing could be too personal, sometimes you wonder whether anyone would learn anything new from it, because you don’t want to waste people’s time! :D But yes, I do that test too, if you re-read it over a period of time and it still resonates with you yourself, it might be worth sharing with the world. I have one base rule, your writing has to be honest. As long as you are truly saying what you mean, not trying to manipulate, not trying too hard to win people’s opinion/favor, it will be good writing.
