Having talked about this very same thing (in a more general context) in our psychology tutorial only 2 weeks ago, I thought it was serendipitous that I encounter this article discussing 4 stages in mastery:

  1. Unconscious incompetence
  2. Concious incompetence
  3. Concious competence
  4. Unconscious competence

Having experienced this progression myself a number of times, I find this concept to be extremely useful in setting expectations when first approaching a new domain.
