Violent Designs,

I made that comment in regard to people who refuse to step out of their comfort zone and do things they wouldn't otherwise do in order to expand their minds, awareness, or sense of self. I did not make that comment towards people who refuse to learn jiu-jitsu specifically.

Nor did I mean to imply that anyone who refuses to put themselves in unfamiliar (valuable-learning) situations is by default "a scumbag", "an idiot", or "intentionally unhealthy".

But: I do acknowledge a significant divide between the personality type that suffers one's self in order to improve, and the one that does not.

Each unto their own.
