Not so new. But good reading. Focuses on emotions in the context of accepting advice.
Brings out the importance of understanding the subject's emotions - state of mind - before attempting to influence her. This is a bit of a digression, but as a KMer, I not only 'am thinking of influencing individuals but also groups of people - mass communication - and that is a different ball-game altogether. It is a paradox that influencing a crowd can either be very difficult due to there being a complex set of independant minds or very easy due to there being a flavour of herd mentality. But then, one must remember that herd mentality cannot be sustained and can only cause harm because of its sole reliance on emotions.
