I'm on a break after getting run down in my last role at the EM / Director level, but I certainly gave a shit, and some of my directs (10-15%?) gave a shit that I gave a shit, and they're now better leaders. Most of this is from their hard work, but I gave them one possible template: genuinely care about your people. My hope is that what I spent of myself was more than made up with what they added. When you're a naive pessimist, leverage is the key multiplier of effective leadership.

one who expects the worst, yet is continually surprised when they get it. Sometimes secretly an embarrassed optimist.

Yeah. I think most orgs have no idea what they are missing.
