Re: dojo frat boys
Once there was a seminar in winter & it was really cold. The dojo was open air, and even though the body heat warmed the dojo up a little, it was still really cold (at least for us Southern Texas guys). The instructor walks by and one of the guys says that he is really cold. The Sensei says for him to "keep his center". After a while the Sensei walks by again, and the student says that he is still cold. The Sensei says, "I never said it would make you warm, just keep your center."
The moral, don't worry about what is going on around you. Just keep your center and keep on training - don't let what is going on affect YOUR training. YOU will be a better person for it.
