Publishing early work feels pointless until you look back and realise the later stuff couldn't exist without it. Same goes for any expressive work. Sounds like a platitude, but it really is all about the process.
Anyway, point is, you read a good post whose goodness was in part due to the thousand posts before it, then think "I need to be as good as this" and you'll fail. I'm sure there's a word for that too.
Easy to forget how long the roots were forming.
