Re: No more Mr. Nice Guy.
Yep, a point I have been trying to make for years, IMHO just because you can get rank and throw people around, doesn't mean you have your ego in check. We all have met a few. I just try hard not to be one, yet know I probably sometimes am.
OTOH, learn from it, what not to do. Just because there is one jerk in (even leading) the seminar, doesn't mean there has to be two. Don't let him take your center and lead you long after the seminar is over.
Yet, I seldom get accused of being a "nice guy".
