..and do you think that you posting it has a positive, neutral or negative effect on the world?
By content I mean what ever you're posting online. The pictures you post on Instagram/Pixelfed or messages you're writing on Lemmy, YouTube comment section, Facebook and so on.
If you look back at what you have posted in the past year for example, do you consider it to be the kind of content that you would gladly consume if it was coming from someone else? If not, then why are you posting it in the first place?
I don't post almost anything online. I mostly just comment. But even the comments I make I sometimes consume as content - I really like comming back and rereading them to enjoy how good and smart I've been.
