Damaged goods

Not everyone who joins a martial arts class is well-adjusted.
Many new starters have a 'chip on their shoulder'.
Some people have their own agenda.

Students frequently want something for nothing, and resent being asked to work for the skills.

Martial arts classes are designed to temper the ego and quash arrogance.
A student must learn patience and humility, respect and consideration.
Invariably, this means not getting your own way.
