Have we lost the ability to say NO?

It seems like more and more business people have lost the ability to say no. That's too bad.  Being able to say no is a higher level skill that is advantageous in both business as well as life in general. Those who don't master the art of saying no are forever doomed to an immaturity in their business skills, while those who can and do say no operate at a higher level of skill and social finesse.
