"Likeable people do better in life in general. They attract more people to them, along with opportunities and invitations. Some say they are likeable because they get more “breaks” than the average person. I think it’s the opposite, and there is a lot of research to back up my opinion. I wrote about the happiness advantage here.

"But if likeable people get further in life, can we become more likeable, or are we dealing with an inherited genetic code that has our gregarious dial preset before birth? No matter what our natural predisposition is, I’m certain we all can improve our likeability factor by changing a few key behaviors."
