I've come accross so many that were written before even I was born that have some fantastic value in them that are more than relevant to todays marketing. The psychology of selling and marketing never 'really' changes, just as human nature doesn't.
The way we act may change, but our core values remain stable. Honesty, Trust, loyalty etc.
So why do so many 'internet marketers' in particular 'slate' these publications that are now doing the rounds again as if they were worthless?
Personally, the more I find and read, the more fulfilled I feel.
Anyone else find this?
