One of the best books of all time is a book by Joe Sugarman called Triggers. I wouldn't part with my copy for anything, it is one of the best books written on influencing behavior I've seen.
Welll, a while back Joe broke down 29 Triggers over 4.8 hours, he talked about how he's used them to sell millions of pairs of BluBlocker Sunglasses and he talks about exactly how you can apply them.
And he did it for free.
He has graciously made that recorded event available to you and me again for free. You can listen online or download it, it is up to you.
I can't recommend this resource enough. Get your copy and listen to it at least once a month, I do and I re-read the book once a quarter. It is that good.
