The slow philosophy is not about doing everything in tortoise mode. It's less about the speed and more about investing the right amount of time and attention in the problem so you solve it.

We know that no algorithm can solve global poverty; no pill can cure a chronic illness; no box of chocolates can mend a broken relationship; no educational DVD can transform a child into a baby Einstein; no drone strike can end a terrorist conflict. Sadly, there is no such thing as 'One Tip to a Flat Stomach.'

We live in a culture that's been hijacked by the management consultant ethos. We want everything boiled down to a Power Point slide. We want metrics and 'show me the numbers.' That runs counter to the immensely complex nature of so many social, economic and political problems. You cannot devise an algorithm to fix them.

There are times when fixing things quickly is the only option: when you have to channel MacGyver, reach for the duct tape, and cobble together whatever solution works right now. If someone is choking on a morsel of food, you don't sit back, stroke your chin and take the Aristotelian long view. You quickly administer the Heimlich maneuvre.

If your business is really easy to do, don't gloat. You might be out of a job soon.

Of the things which nourish the imagination, humour is one of the most needful, and it is dangerous to limit or destroy it.

A Princess of Mars' may not have exerted the same colossal pull that Tarzan had on the global imagination, but its influence on generations of readers cannot be underestimated.

Precisely at the moment when an athletic career is most on the line and fan perceptions of a Herculean, supra-human performance are highest, an athlete's brain may be at its most vulnerable.
