sparking curious mind

Rory Sutherland does an excellent job of selling what he calls "intangible value".
By the end of this talk, he will have persuaded you to the notion that intangible value is good, because it prevents people from only wanting more all the time, and instead enables them to appreciate what they already have.

A very valuable and insightful talk - sometimes it is a bit over the top - but we can give that licence to him - he is an advertising man and speaks his business well.
