IN answer to a question at The mentality behind martial arts
Firstly, you tear down all false sense of confidence. Then you push the poor bastard past all pre-conceived notions of his abilities. Then you throw hell at him, and then some. The bloke eats all of this up and starts to show gains in skill level. Teach him good principles. Show him wisdom. Teach him discipline. Show him how to survive, to thrive. Share with him your lineage. Entrust him to be the guardian of the syllabus. Teach him how to nurture beginners in the path. Then groom him as your successor.
Most people however, give up just at the time when they're starting to learn the basics ... that's not even anywhere near the starting line.
