It is worth watching. The bloke sounds like a bit of a yank spin pusher -------------- but, unfortunately - his track record is very good - not perfect, but bloody close.
If you can prove to yourself that he is not full of crap - I suggest by looking at what he wrote in 2006 and you can get over that he sounds like a salesman -----------
then it is very hard to argue that, 1. this bloke just might know a thing or two and 2. We ain't seen nothing yet.
I know 40 minutes sounds like a death sentence - but I will tell you what -------- I wish I had known about this bloke around 2007.
