The 2ndBrain Way, in order

1. 1
   The one-page brief becomes a working thing

   In one hour, on a free Replit account with nothing installed, one task that gets written down twice becomes a page with a form that writes to a table, and you can say the four ways it breaks.

2. 2
   The daily capture

   By the end of any day, every loose thing from that day is in the Inbox file in your own words, and it took under ten minutes.

3. 3
   The map, not the territory

   A one-page index that points at where things are instead of holding them, so you and any assistant can find anything in one hop.

4. 4
   The one-job build

   One recurring task, said in one sentence, built to run without you, and you felt it go away inside a week.

   Start unit 4
5. 5
   The handover test

   You can run the build without the person who built it, and you can name the three places it breaks before it breaks on you.

   The four-write loop: the system learns

   Your assistant does not make the same mistake twice, and you can open the file where it wrote the lesson down.

7. 7
   The receipt sweep

   Every claim you make about what got built carries a receipt: what it cost, what it saved, what broke. One sweep a week, posted.

   The room as the school

   You gave one thing back, credited to you, findable by the next person with your problem. That is graduation.
