Interacting amiably with family and friends is a super stress reducer. Instead of the mind working overtime on worries and problems, it is occupied with thoughts of other things and other people. There is less mental capacity left for anxieties and self-doubt.
"Friendship improves happiness and abates misery by the doubling of our joy and the dividing of our grief." - Marcus Cicero (BC)
Good friendship is healthy but it isn't easy for everyone. Getting people to like you is the starting point, and that should be fairly easy to do. People have a basic need to be liked themselves. Show interest, appreciation, and kindness. Smile. Praise given out sincerely is a great act of friendship. Be a good listener and try to see the good, not the bad qualities in people. These actions will usually be returned to you, sooner or later.
"The only way to have a friend is to be one. . . A friend is a person with whom I may be sincere. Before him I may think aloud." - Ralph Waldo Emerson (1803-1882)
As a friend, try to let an unfavorable incident or remark fly right over the top of your head. We all blurt out something stupid or do something regrettable at times, and it's so nice when the other acts as if it never happened. This is a dear friend.
"The rule of friendship means there should be mutual sympathy between them, each supplying what the other lacks and trying to benefit the other, always using friendly and sincere words." - Buddha (BC)
