Actually, this post by Art Petty is more about leadership excellence: the link alludes to leadership caffeine, which is more to the point. His central point is that intensity can’t be too high or low.
It seems Art is saying that leaders should use something like situational leadership: there are times to firm, times to listen more, and so forth. There are no times to yell and scream at your direct reports, though.
It’s a fine line, leadership. Too firm and people think you’re authoritarian. Listen too much with no comment or clear direction, and your troops will think you’re to passive.
And, where does passion fit in? I’ve know leaders who were passionate about something who would practically jump on tables and rant away, when normally they were pretty well balanced.
Anyway, here’s the link to Art’s post: http://artpetty.com/2013/02/04/leadership-caffeine-4-rules-for getting-intensity-right/
