“That survey revealed that health is the prime interest of adults and that their second interest is people; how to understand and get along with people; how to make people like you; and how to win others to your way of thinking.”, Dale Carnegie in “How to wind Friends and Influence People.”
“I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.” Maya Angelou quotes (American Poet, b.1928)
And this saying lies at the base of the secret on how to make people like you. Respect sensibilities in other people with a sensitivity they appreciate. The ego is the greatest stumbling block we have in us. It is the “I” that others don't like and it is the “I” that puts up barriers to others liking you. If we can put the “I” into the background and focus on the other person, praise him or her and say a word of appreciation, it is a start to being liked. Respect for others gains respect for you.
Also, there is the element of graciousness that is of great use in developing relationships and maintaining them. It serves no useful purpose in telling other people of their mistakes directly. Instead one can use gentler words and indirect fashion of speaking to not hurt any one. Criticisms come easy but criticizing oneself before we criticize others will make us better. Then there are also ways of asking another person to do something. You could order and appear imperious and overbearing or word it in a way that elicits a positive response. Simple words like “I wonder if you would help me out on this one..” work magic. The other person will do it for you-- gladly.
Then again your graciousness shows in the way you do not let anyone lose face—either publicly or privately. Mistakes happen. Even if you do not get on well with a person, always look at his positive aspects and speak of them. Sooner or later that person is going to become your friend and like you. Smile and the whole world smiles with you and when you say something unpalatable softened with a smile, it goes down much better.
People want others to recognize them and in a rush they keep talking constantly about themselves. This can get rather boring and might even be a turn off. Instead, encourage others to talk and show interest sincerely. It can get to be a good habit you cultivate to your interest. Giving importance to the other person's perspective and views is an important step in being liked. Coming across as a positive person people like to talk with creates a favorable impression.
Discussions and arguments happen in life. But if desire to prove himself right and come out on top, it can create friction. Avoid argument altogether. If at all there is a difference of opinion, it sounds much better to say each is entitled to his opinion and that you respect the other person's views and opinions. If one is wrong, there is no shame in admitting.
Sometimes, people want credit even for the smallest thing they have done or even take credit for something someone else has done. It does bolster his ego and supposedly earns him fame. However, it is not going to make him a very likable chap. Opening up outwards like a flower towards other people brings the horde of bees of people buzzing around you and liking you.
