# Reference vs Lessons + Mission — retrieval verified

1. Correctly identified the different purposes: lesson = knowledge delivery (temporary, avoids cognitive overload), reference = compressed essence (permanent, for quick reload and review). Applied Lesson 0002's Knowledge layer concept to explain this distinction.

2. "没有mission，会混乱，会跑偏" — without Mission, six lessons become random topics with no unifying thread.

3. Started drafting next MISSION.md unprompted: "学习他理解世界的方式/分解复杂问题的能力，最终用来解决自己的问题" — this is concrete enough to drive a full lesson cycle.

## Implications

User has fully internalized the template. Next step: create a new teaching workspace for Karpathy or the next learning target. The teach skill methodology is now operational.
