Hello Antonis. I am from Greece also, but go to a different dojo, Kobukan. I started Aikido on September and received my first "promotion" from 7th to 6th kyu on December the 17th (boy, was I anxious or what?!)
Anyway, my point is that YOUR OWN time will come, when YOU will feel up to it and noone else.
C u around,
Joyce
