Well, see, when you meet a person what ordinarily you will do, if you are interested in him? If you meet any stranger and if you have a fellow feeling, a genuine heart, when you meet the stranger if you are a gentleman, if you are normal, would you talk about yourself? Is it a good culture even to talk about yourself? 'I, I, I, I, I. I did this, I did this, I did this, I did this'. If you have a fellow feeling naturally you will be interested in others. You will be interested to know him. And then if you are interested to know him, you talk to him. You try to know more about him because you are interested in him, not because you have to befool him. So ultimately your behavior also may appear as the same as what Dale Carnegie says. Though you may not praise him but your sympathy for him, your interest in him and your talking less about yourself and more curiosity, more interest to know about him that may serve the same purpose. But see the world of difference, see the motivation.
One may be honest because honesty is the good policy. To adopt honesty just like you wear clothes, in the same way your wear honesty. Why? It is a best policy. Ultimately you will stand to benefit. To be honest because honesty is the best policy is one thing and to be honest because 'it is the article of faith in me. I cannot be dishonest. Whether it is good policy or not, I don't know, I cannot but be honest. I don't follow honesty because honesty is the best policy. Honesty also gives you sufficient benefit. How far this honesty is beneficial, how far it is detrimental to my interest - Calculating all that, I have not decided to be honest. I am honest, I feel like being honest because it is an article of faith in me. I cannot be otherwise'. So with what motivation you do that is important.
