Yes, actually you ARE ready for graduation

Okay, it's rare, but sometimes I do have students who are ready to graduate even though they think they need more time.  Often this happens for Black Belt exams, since we would all like to have more time to prepare ourselves for those.  As an instructor, we have to make sure students are mentally and emotionally ready so they don't get stagnant or complacent.  For them, it's about facing fears and taking on challenges.

Sometimes it's about the elusive perfection, or a student has compared themselves to someone else in class.  Either way, the instructor has to remove that student's self-evaluation (which is flawed), and establish the proper standards for progress
