You're already doing it
Artifact: the next real, small thing you'll build, named here and committed to
1. The only graduation
There is no point at the end of this course where you graduate. There was never going to be — readiness is a feeling, not a state, from chapter 2.
What there is, instead, is the moment you notice you've been doing the loop without thinking about it. Predicting before you run, because that's just how you read code now. Building the smallest real thing, because that's just what you do when you want to learn a tool. Saying it back in one sentence at the end of a session, because the sentence is now the natural way you close out a day.
That's it. That's the graduation. It is quiet, and it happens to people who weren't trying to notice it. If you're still reading, you're closer to it than you think.
2. The thing you take from this course
If you forget every single sentence in this course and remember only one thing, make it this:
Learning is what happens when you produce something from inside your head, find out you were wrong, and update.
Everything else in this course is a way of arranging your time so that more of those moments happen. The whole curriculum collapses into that one line.
3. The main thing
The main thing is the next thing you build, today or tomorrow.
Pick it. Predict your way through it. Try the small real version. Check whether you were right. Write down the one sentence.
That's the course. That's also the rest of your career, if you keep doing it.
Go do it.
