I disagree. Writing is a creative exercise like, say, music. Artists write bad albums and within good albums, there are weaker songs. But all of their pieces, good, bad, and average, are reflective of their journey, their evolution, and true fans usually appreciate the unevenness of the material. And Of course, technically can’t unwrite the stuff already released. Cherry-picking your high-quality stuff is like plastic surgery in my opinion. You end up fake and ugly... It’s ok maybe to delete sometimes, considering Medium is about casual writing and blogging, but 80% sounds wrong to me.
