You can get along with everyone. Wherever you go and whatever you do, people are just about the same. They are no more difficult to get along with in one business or in one place than another. Every individual has his own problems, his own worries, his own interests and desires. All you need to remember is that the art of getting along with people imposes some personal obligations on you. You cannot afford to lose your temper; you cannot be a gossiper or rumor-monger; you cannot pass the buck to others and evade your own responsibilities; you cannot overlook the little courtesies and kindnesses that lubricate your many daily contacts with human beings.
If you will, you can make a friend of everyone. Even your enemy can be converted. He in particular must be converted, for an enemy can do more to harm you than half dozen friends can do to help you. A wise man once said, “The only safe and sure way to destroy an enemy is to make him your friend.” And in the process of trying to convert him, you will see many of your own faults, too, thereby making it easier for you to make him like you.
Don’t forget that the other fellow is just as important to himself as you are to yourself. Thus, you will learn to approach him and handle him in the same careful manner that you would handle yourself. Remember that you may never tamper with the dignity of another human being, any more than you would want him to afford you. All these things help you to develop a personality that is cheerful, likeable, and affable – a personality that is impervious to trouble.
