Knowing yourself is the first step towards extending any relationship. Be confident about what you are speaking and what you are doing.
If you are good at sports, show off this particular plus point in you, if you are a good cook, cook well and prove yourself, if you are very smart, show this in your words and actions. People get impressed when you are self confident and know yourself.
Communication is the key for any relationship. So look for a person with whom you can communicate very well and put across your thoughts. If you meet a person with like minded thoughts then it’s your luck. But remember not everybody can have same thoughts and likes and no two people are same.
If you are a boy and trying to have a relationship with a girl, then have as much communication as possible about the topics she likes. Don’t speak about any relationship which you would like to have with her. Just be friends with her for a long time. If you feel she is a suitable person for you, then express your feelings for her. Remember, most girls generally are, or pretend to be introverts.
Don’t lie at any cost. One day or the other the truth will come out; you will end up telling 100 lies to save yourself and finally loose face. You will loose the nice relationship you have built also. Do try not to lie.
Indirectly make that person realize that you like them a lot. You don’t have to flatter all the time to make them feel this. Just make them realize this, by giving a lot of importance.
When you would like to go into a relationship don’t flirt. Generally people become possessive about each other within no time and your flirting attitude may hamper your relationship.
Take things as slowly as possible. Make sure that the other person is totally comfortable with you and has a lot of trust in you. This itself means that you can have a relationship with that person.
