8. Don't forget your manners
Any time I witness good manners--"Please," "Thank you," or "Please, you go first"--I immediately take this as a sign of a good person that I can trust. Good manners and being humble always leave a great first impression.
9. Just relax and be yourself
Remember that most people are just as uncomfortable or anxious as you are during a first meeting. Tell yourself that you are good enough and see what you can do to make the other person more comfortable--if they're comfortable, you will be more comfortable. So take a few deep breaths, relax, and go be your fabulous self.
