An expression I love is "a rising tide lifts all boats."
I agree with you that it is about community. Showing up here with pure intent, as you are doing, is so important. You are doing very admirable things: creating great content, helping your fellow writers to produce great content, and supporting quality content through curation. I believe those of us who adhere to these values will rise above the steaming mass of sub-par crap, while motivating others to do the same.
Thank you so much for the mention!
