Good advice indeed!
What I found to be the case for me on Steemit is that others' articles inspire me in a roundabout way. When I read an article which I find myself capable of adding a decent comment to, I finally find that my comment is written in a form that I can turn it into an article, with some minor changes here and there.
Yesterday I too wanted to write a new article (I have about two dozens left accumulated over many years), but I found no inspiration. Then, I had this idea of skimming over my comments, and one hour later I had 15 new articles that now add on to the two dozens I had already.
I released one yesterday, and I really guess it is the mind barrier which always wants to make it perfect. But what is perfect in our view might be received differently by others. So I just dropped my article without much expectation or thought, and it doesn't perform any worse than my others :)
And: people's attention span is relatively short anyways these days, so it does not need to be as long as we sometimes might think :)
I've found that Steemit comments, both mine and those I read, are excellent writer's block extinguishers for me as well!
Your absolutely correct- these days people want their information fast and concise.
