I’m asking that you start with thinking. I suspect, if you’re a reader, you’re already a thinker—which means you’re halfway there. Really. Because writing—that first leap into taking your idea and making it a Thing People Read—isn’t really about wording. It’s about thinking. And if you can tell the difference between an article that knows what it’s about and one that exists purely to sell ad space, then you’re pretty good at that already.
Think about the things you had to look up on the internet just to figure out how to do your current job. Or maybe those things aren’t even on the internet—you learned from direct experience. You should write that stuff down, because when you connect your ideas into a written piece, you give voice and direction to something that otherwise just rattles around in the form of entrenched habits and beliefs—a resigned “that’s just the way we’ve always done it around here.”
