Another book (or "book") with a great truth — let's all take care of each other — and not much more. Movingly-told anecdotes, yes. Testable, statistically-based evidence? Not so much, if any. Pop neurochemistry = endorphins + dopamine + serotonin + oxytocin — plenty of it. Bottom-line-up-front? Still looking for it. Simon Sinek's Leaders Eat Last: Why Some Teams Pull Together and Others Don't — an excellent 2009 TED Talk, in 300 pages.
