Module 1 · Hook
Pick one system. Build that first.
A real system is too big to build in one move. The skill isn't doing it all at once, it's compartmentalizing: break the goal into systems, pick ONE, and build that first. You don't launch the whole starship. You build the first part that flies.
The job
When the thing I want to build feels impossibly big, I want to break it into systems and pick the first one, so that I can start today instead of staring at the mountain.
