Over the past five and one half years and almost 1400 posts, I've worked assiduously to avoid repeating myself here. The robust search feature on Blogger has been a huge help.
Unfortunately, using that search feature sometimes leads to what some artists might consider a solipsistic downside, i.e. I occasionally re-read my older stuff. How many times have you heard famous musicians say they never listen to their own recordings or famous film or TV actors say they never watch old performances? Aside from the use of the absolute "never" - itself a red flag - what I frequently wonder hearing statements like this is how these artists mark their growth if they don't occasionally contrast older work to more recent. And more pertinent to my thrust here: How do these folks ensure they're not repeating themselves without an infrequent glance backwards? If you're a recorded musician, a writer or visual artist of any kind, an actor who has been captured on film, do you never re-visit your older work?
I try not to dwell in the past, either with my writing or otherwise. On the other hand, I find significant wisdom in William Faulkner's words - "The past is not dead; in fact, it's not even past."
