Interesting find, John. I agree with Bob on some points, but others I don't. I guess a lot of it all depends on your life style. Bob is obviously a very busy man with not enough hours in any one day. In the section referring to cold callers, he makes some very good points, anybody in their right mind shouldn't think they owe the caller anything, sure, we have all been there, in the past I have decided, sub-consciously, I at least owed them my time, but these days, I tend to simply say I'm not interested, and put the phone down, there have been a number of times where they carry on talking and I hang up, I have no guilty feeling in doing this.
It is where Bob gets to the people who you know personally where I don't agree with him. Personally, I go out of my way to make time to speak with people I know personally, even if it is business related. I do feel I owe them this, certainly if they are calling for advice, they believe I have a quality they want to use, so I at least owe them some time and advice.
