Negotiation for Life and Business

IVE BEEN INTRIGUED for some time by negotiationthe skill used to influence and change minds.
Changing or influencing a mind is about convincing another person. To convince someone, one cannot point a gun and demand Agree with me, although some apparently do. Aside from this approach being immoral, it wont work because people have the freedom to make decisions for their own interest and force is not a convincing factor.
I dont condone or admire those who are on a mission to change the entirety of others. This is not negotiation. People have particular prejudices and belief-systems which must be addressed and worked aroundyou and I as well.
