The apprentice model. You have not mastered a skill until you have taught it and the student passed.
- Learn — absorb the canonical material. Unanswered questions are documentation gaps.
- Do — execute on real work under review, not hypotheticals. Repeat until consecutive clean runs.
- Teach — transfer it to the next person. The teacher then owns review, and the senior climbs.
This is how trades have always scaled. Digital marketing is no different. The cobbler with no shoes is not a teacher. The SEO firm whose own site is a wreck is not an SEO firm. Practice what you preach. Watching YouTube is not an apprenticeship.
Pairs with SBP. Learn is the specialist. Do is the business. Teach is the partner.
