I generally agree with the piece, especially writing as discovery. And I certainly identify with the opening being hard--in fact, there's a good argument for putting something there so that you can get on with writing the rest of the piece. I've sometimes probably spent a decent portion of my total writing time figuring out a hook/analogy/etc. for the rest of the piece.
The thing that's missing is that you also need another pair of eyes at least for anything beyond a personal blog post where it's somewhat OK to have mistakes. Obviously you can't get at least a copy editor for anything but you basically can't publish even a short book, report, or something like that without someone else doing a careful read.
"And don’t neglect a second pair of eyes: Ask relatives and friends to read over your work. They might catch some things you missed and can tell you when something is amiss."
Fair enough. I missed that near the end. Although I would say that casual reads by colleagues, friends, etc. tend not to be very careful. If it's important you probably need to pay someone.
