How to Win Friends and Influence People by
Dale Carnegie, 1936.
Control your temper. Remember, you can measure the size of a person by what makes him or her angry.
Three-fourths of the people you will ever meet are hungering and thirsting for sympathy. Give it to them, and they will love you.
Ask questions instead of giving direct orders.
Remember that a person's name is to that person the sweetest and most important sound in any language.
The unvarnished truth is that almost all the people you meet feel themselves superior to you in some way, and a sure way to their hearts is to let them realize in some subtle way that you recognize their importance, and recognize it sincerely.
Talk about your own mistakes before criticizing the other person.
Everybody in the world is seeking happiness - and there is one sure way to find it. That is by controlling your thoughts. Happiness doesn't depend on outward conditions. It depends on inner conditions.
Make the other person feel important - and do it sincerely.
Let us praise even the slightest improvement. That inspires the other person to keep on improving.
Let the other person do a great deal of the talking.
