It's not possible to make everyone like you. In fact, one surefire way to make everyone -- or nearly everyone -- dislike you is to try to make everyone like you. There aren't many things more obnoxious than people trying to get everyone they meet to like them. You can't be all things to all people. People who try are phonies, and sooner or later people figure them out. You must learn to be yourself. Pretending to be what you're not just to win approval from others is bogus. That's not to say, however, that you shouldn't work at improving yourself -- in appearance and attitude -- and by trying to be friendly and outgoing. That can be very difficult, for sure, particularly if you are inclined to be shy. But with the proper encouragement, you can build up confidence and feel more comfortable around new people without giving the impression of trying too hard.
