Most difficult CEO skill? That's a life skill. Not to dismiss how hard it must be to be a CEO because I couldn't imagine it but those lessons apply everywhere. Replace the word CEO with the word life and you have an article about how to manage the stress of everyday life.
Edit: I really really don't want to sound dismissive, that's really not the intent.
Like I said, I wasn't saying that. I wasn't being dismissive. I was just observing that this is a skill that applies very broadly. I read it, got it, liked it, then thought "hey, that actually applies everywhere". It's not a knock against the author or the article. Just my reaction.
