People who start learning jiu-jitsu... 90% of people who walk into a school, what are they looking for? They're looking to be able to defend themselves against someone who wants to take something from them—take their dignity, take their property, take their kid. If someone wants to threaten you, you should be able to defend yourself and not get hurt. And even if they're bigger than you are, you should be able to do that—because someone will try to take something from you, even if it's your dignity... You have to be able to stand up for yourself.
