Conflicts are not only inevitable, they are necessary.
As long as there are people, there would be different point of views. It is important to realize that each point of view is correct from its own perspective. I am sure you would have noticed that the other person, in the conflict, is as convinced about his point of view as you are about yours.
Make space for conflicts. Accept them as an inevitable part of life. In a conflict, try to see the other person's point of view, and also welcome the person to see your point of view. Even if you are not able to see the other point of view, accept it to be as true as yours. It may be because the other perspective is not visible to you. Conflicts are necessary, because they force you to look at other perspectives.
The only way to avoid conflict is to live in isolation.
