Why waste all your charm on new people who you don’t know very well? You should focus on the people who already know and appreciate you. They deserve the benefit of your wonderful wit and warmth more than anyone else, don’t you think? If you spend all of your energy trying to put on a show every time you encounter someone new, what will you have left over for the people who stand by you through thick and thin? Let new people work harder at impressing you for a change.
