Nothing is more simple than greatness; indeed, to be simple is to be great.

Complication is usually a sign of not yet understanding something well enough. The person who really grasps a subject can say it plainly, while the one still finding their way needs the scaffolding of jargon and qualification. The same is true of character, since the people worth most tend to be the least complicated to deal with.

Take something you have written or plan to say and cut it until only the load-bearing part is left. If it collapses, you have found what you did not actually understand. Plainness is not a lack of sophistication, it is what sophistication looks like when it is finished.
