I think the most difficult part about being in a relationship or the threshold of a relationship is to be yourself. When you have this fact in mind that you have to put your best foot forward, you tend to overdo things to impress your partner. You get this feeling that you must be better than what you are as a person and you try to prop up the weak sides of your personality. For example, if you are an introvert, but your partner is not, you tend to talk more and act louder than you would do normally. This is the biggest mistake that you can do. When you fake to be someone that you are not, it’s either noted by your date immediately, or it becomes transparent in a couple of meetings. Then you are generally taken to be a fake person.
Guard against that. Be yourself. You are a unique individual and people will only respect you if you respect yourself. There’s never any gain in trying to be someone else. If you feel some improvement is necessary, do it with the idea in mind that you can be a better yourself, but you can never be a good someone else. You would want your partner to know the person you actually are, and if you try to cover up the real you, you only make things difficult for your partner. The base of any relationship is trust and honesty, and it begins with yourself.
Be comfortable with what you are. A person at peace with himself will no doubt attract attention. No one wants to meet or talk to a person who appears to be a poor replica of someone else. When you maintain your dignity and self respect, it shows and you have a better vive going off you. Never be envious of personality traits that you do not have. There are many traits in you that others do not have. Exploit those to your advantage and you’ll feel the change in the response of the people towards you. Try it and let me know if it works!
