I'm no fan of the World Economic Forum. It seems to be run by a bunch of filthy rich psychopaths intent on depopulating and enslaving the world.

That said, I'm sure everybody who's ever been involved with them hasn't necessarily joined the dark side. But even if they've completely sold out, I'd bet the 0.017% of a Bitcoin I own we could still learn some valuable lessons from these hyper-successful businessmen.

For example, in one of my favourite books, Essentialism: The Disciplined Pursuit of Less, Greg McKeown tells the story of Geoff Davis, one of the World Economic Forum's Young Global Leaders.

Geoff Davis is also President and CEO of Unitus, a social venture capital investor for a global microcredit organization which claims to have helped 12 million poor families around the world. He is also on the board of Kiva, a non-profit which crowdfunds loans to help third-world students pay for their tuition and start their own businesses.

He doesn't exactly sound like the anti-Christ.

But who knows?

Anyway, one thing I do know, and Davis knows now, is that he wasn't sleeping enough.

For years he slept only four to six hours a night.

By the "ripe age of thirty-six…" explains McKeown, "one by one each of his organs started shutting down. His heart rate was erratic. It became painful to stand up straight. He had to blend his food because he could not digest it. His blood pressure was so low he blacked out if he stood up too fast. He went to the emergency room twice."

But he kept forcing himself to keep working until… he found himself cancelling meetings at the last minute because "he was too weak to attend or he would give a speech but bomb it because his brain was cloudy."

His doctor gave him two choices:

1) A long list of drugs that would treat his rapidly growing list of symptoms which he would have to take for the rest of his (probably short) life or…

2) He had to take time off work.
