Relationship. It's not all about love. One need to have to have the courage to face and overcome future obstacles too. If you're an egoistic person or a temperamental person just like me, being in a relationship can be a daily lesson to you. At times, you will learn to put your ego aside and sometimes you will learn to calm yourself down easily than when you were single. In life, nothing is easy. Obstacles in life makes you more mature and stronger.
