Dress nicely when you go out on a date.
Wear a dress or a nice blouse with a pair of jeans. Style your hair with a curling iron or wear it up in a neat bun. Apply some mascara to open up your eyes and wear blush to brighten your complexion. If you show up to a date looking messy, you give the other person the impression that you don't care.
Compliment your date when you are together.
Tell him that his shirt is nice or that you like the smell of his cologne. If you make your date feel good about himself, he will appreciate that you took the time to notice his appearance.
Ask your date questions about himself.
Find out what he does for a living and ask him about his hobbies. When you can't think of anything to say, always try to come up with a question for him. This way, you can avoid awkward silences, and he will know that you truly want to find out more about him. Avoid asking questions about his political or religious views in the beginning, so he doesn't feel uncomfortable.
Be honest with your date.
Do not tell him that you work at a Fortune 500 company or that your cousin is a famous movie star to impress him. If he finds about your lies later, he will have trouble trusting you. Recognize that the real you is good enough, and that you don't need to embellish your life to get someone to like you.
Do not lead a person on if you are not interested in him.
If you deceive him by pretending you like him, you will only hurt him in the end. If you don't want to see a person again, tell him that you are not interested in him romantically.
