Relationships play a vital role in deciding quality of your life if we have good relationships, friends, colleagues, life can be really be very beautiful , more joyful. 

I believe that these couple of things could be helpful in understanding relationships.

1. A relationship is like a seasaw. If person "A" is in up position that means he is dominating, with Person "B" in the down position.

2. If one person is not dominating the other will automatically start to dominate, and ideally a relationship should be like a balanced seasaw in which neither person dominates.

3. To make a relationship stronger day by day, always treat the other person in the manner you would like to be treated.

4. If you are good as human being,  you will have more success in having stronger relationships.

5. In relationship, a negative act of yours is remembered more by the other person than a positive act.

6. While choosing to have a new relationship with someone, always give more importance to intangible things like the nature and qualities of that person.

7. Give less importance to tangible things like money, luxury, beauty, etc:

8. Always think twice before speaking or acting.
