In regards to the "you've just started to learn" aproach to shodan, I think this is one of the most correct sayings. I still don't feel that I've "earned" my shodan (november 2012), but I have tested in a JKA grading, and proven to be at the required level. I feel that i have "earned" it in the case of the effort and years I put in (6 years). But in regards to fluidness, knowledge and correct technique (all the small odds and bits that make a correct technique) I still have a looong way to go. It's been deemed good enough, but it's far from perfect. This gives me a boost, that I have achived shodan, but still have lots of tings to learn. It's great! Black belt after 3 years... Naah, don't think so.
