Catlin Tucker shares 5 Musts for Mastery, prerequisites for mastery learning to happen. Tucker states that we can master a concept or skill but that is not the endpoint. Absolute mastery is out of reach; there is no dead end in learning. His '5 Musts' may seem surprising to you, but in reality they are not 'mastered' but are important for real learning to take place.
