I write courses to learn things properly, then leave them here.

Every course here started as something I needed to know and could not find written down honestly. Writing the lesson is how I find out whether I actually understand it. That is also why some courses are a spine with four lessons attached, and why that is left visible rather than hidden.

How it works

• An account is optional, and does one thing. Everything works signed out in this browser. Signing in keeps the trainer’s practice schedule and your finished lessons in step across devices. Nothing else is uploaded, and there is nothing to buy. What it stores.
• The whole course is declared up front. Lesson 19 has a number before it has words, so the ordinals never move under you. A lesson that is registered but unwritten is listed and is not a link.
• Every claim links to its source. Each course keeps its own list beside the lessons that lean on it. If a source is paywalled or gone, the entry says so where the claim appears, rather than quietly dropping it.
• A teaching agent does the tutoring. The lessons are the scaffold. The conversation is where you get unstuck. I do not run a forum.

What this isn’t

It is not a product, a cohort, or a newsletter funnel. Nothing here is for sale, and I have no plans to change that. If a course helps you, that is the whole return.

Some of it is visibly unfinished on purpose. A course I am halfway through is more useful published than waiting in a draft. The numbers beside this text are the honest count of how far along that is.
