The newsletter "Cut the Fluff: Authentic writing is a myth" challenges common fears about self-editing in writing, particularly the concern that cutting words will sacrifice authenticity. It argues that cutting unnecessary or unclear content actually enhances clarity and reader engagement. The author emphasizes three mindset shifts to support this: first, that editing is beneficial and not a destructive process; second, that authenticity in writing is more about personality than preserving every initial word choice; and third, that instinctive writing isn't always optimal and should be refined through editing for smoother, more impactful communication. The article encourages writers to embrace editing as a means to refine their voice and strengthen their connection with readers, debunking the myth that authentic writing is synonymous with unedited spontaneity.
