Unfortunately I think the majority of the advice is worthless if this appliies:
If decisions are made based on personality and emotions instead of data and discussion, it will make everyone “stupid”.
Which I have sadly found to be the case in many of my work situations.
Hope it doesn't apply absolutely.
Because I don't see how personality or emotion can be completely avoided when anything of genuine importance is at stake. Now that I think about it, I can't say I've ever once been in a situation where a significant decision got made that was
totally devoid of personality or emotion.
Not that either is necessarily a bad thing. It's only when reason is completely subjugated in favor of them that things tend towards stupidity.
Just because we're not Vulcans doesn't mean we're doomed to act like monkees.
BTW: Does anybody else think that monkey looks just like Martin Scorsese?
