Stubborn

Gratefull and earnest :  two things that are simple and crucials in our life. In contrast, those are difficult to do because of the ego, selfish, and also stubborn. Maybe stubborn is a part of the ego. It is a character that cannot accept what the others opinion is. Stubborn persons think their opinion  is better than the others. This character have the advantage and disadvantage effects.

 When someone wants to keep on their opinion in the right way and believes for something real, true, and admitted by a lot of people, it will give benefit to the others. It is because they cannot be influenced by  anything. For example, someone believes if corruption is a bad thing. Even though there are many people surrounding him do that, he cannot be influenced. Furthermore, they will have a lot of enemies (from the opposite ideas).
Basically the stubborn persons can be known from how hardly he/she keeps his/her ideas. They will always say "NO" for something we believe its "YES". Means, theirs is always the best.
In responding their ideas and then conclucing wheather this is right or wrong (in general perspective), it depends on where we see the case from. If the ideas is against to general truth, we can say that they never can be understood.
Then how to make a good social interaction with the such a kind of person?
There are some ways to do :
Firstly, do not oppose them by the frontal ways. Just tell them wisely.
Secondly, show them the logic arguments (evidences) that makes them believe and stop showing their egoistic.
Lastly, face their stubborness with simply approach by saying : "you are so strong, so powerfull and FUNNY"  (editor :  Mr. "O" Abdul Redjab)
