That’s a dippy question. I know our interconnected age is supposed to offer access to the world at each and every keyboard or touch screen but seriously. Sitting in a sea of content, bashed out with increasing frequency, only a fraction will bubble to the surface.
If you think you are indispensable, dip your finger into a glass of water and then remove it. Observe the hole. That sarcastic little saying deflates the ego. On a positive side it lowers expectations, so success then comes as a wonderful surprise.
The vast percentage of what’s written is forgotten. There’s more that is ephemeral in heaven and Earth than I might care to think about. That’s a good situation to be in. Time plays a part.
Recounting the number of artists or writers who were ignored in their lifetime but celebrated after a couple of generations down the line, that’s a big list. I suppose it’s not possible to know when a person’s words will be a catalyst of change. It would be nice to be as astute as say, Carl Sagan, and quoted endlessly. A league of thoughtful communicators that are memorable.
Striking that public resonance is within the bounds of a few. Personally, my scribblings are for me. If others like them then that’s great, it’s not the reason to scribble.
