The hard part is the vulnerable voyage into the self, as we clarify and challenge our thinking as we express it with real words. Our goal should just be to say things that are true, as simply as we can. We should start by figuring out what a novice should know about a topic, and then communicate that before moving on to the next thing. Word by word, this can compound into a book or a larger article that can even prove an advanced grasp of a topic, and be genuinely educational to others.
