Dating can be fun and exciting, but it can also be stressful and overwhelming. To win affection, some people hide certain aspects of their personality, are dishonest about their opinions, and pretend to be interested in topics that they are not.
If a relationship does result from faking your personality or interests, then that relationship will be based on a lie, not honesty. You will be liked and admired for the person you are pretending to be, not who you are. Inability to express yourself freely to your partner will make it impossible for you to form a genuine connection with them; there will always be an unspoken emotional barrier, which won't be fair to you or your partner.
Rather than trying to impress the person whom you are dating, your goal should be to express yourself freely. If your date is put off by your behavior, then take it as a sign that the two of you might not have enough in common to make a relationship work. Now, this does not mean you should be disrespectful; you can express yourself kindly.
Being yourself and speaking your mind can be frightening, and it undoubtedly takes courage, but no matter how difficult, you must remain true to yourself at all times. Being honest and upfront about your beliefs, feelings, and opinions will cause some people to lose interest in you. However, it also enables you to form a real connection with someone with whom you are truly compatible.
