Why do you encounter the same conflict over and over? Probably because you are using the same strategy you have been using many times before. Conflict resolution is not achieved because for you it is. Conflict resolution works best when those involved can identify the particulars that make this situation different from the last.
Successful problem solving requires you to look at all situations with a fresh perspective no matter how similar they look. The hiker above may have crossed the stream from the same point a hundred times, but he has never crossed it the same way twice. Why?
Water flow and levels are in constant flux due to rainfall. Water temperature varies with the weather. The stones on which the hiker steps on are weathered or not in the same place. These are but a few of the changes that exist each time the hiker crosses the stream even if it is at the same point.
It is futile to imagine crossing the river in exactly the same manner. Similarly, there is no point in looking at the same student, child, or employee sitting before you in the same regard as the last time you were in a conflict resolution situation with them. No matter how familiar a conflict feels, there is always something different about it.
What is different this time? How can this difference play a key role in resolving the issue? How can you get those involved in the conflict — possibly you — to see how these key nuances could get you to a resolution, just like the hiker has to roll up his pant leg higher because the water level is a bit higher than the last time he crossed due to the excessive rainfall the day before.
