For those of us who cannot attend David’s day-long presentations in various parts of the world, here’s David’s talk at a Barcelona bookstore, in three parts. David’s presentation covers many things he’s said before, but I suppose I for one never tire of hearing it. In my opinion, he must be one of the world’s best presenters. Thanks to Len.
