How to solve an argument.

1. Define the problem.
The more people there are the more difficult this is so spend some time on this one. Also if you do not make this clear enough, much time can be wasted while different people are trying to solve the wrong problem.
2. Brainstorm solutions
This is not the time to evaluate the solutions. Anything goes. Try to come up with at least twenty and let some of them be offbeat ones. It is the offbeat ones that can sometimes lead to real solutions. If you start saying things like, no that won't work, then very quickly everyone starts shutting down because they evaluate it in their mind and reject it. Just write down whatever is brought up whether you think it is a good idea or not.
3. Evaluate solutions
Now is the time to go over the solutions and evaluate what will work and what won't. Don't be afraid to pick a couple or a combination of some of them. Always pick a back up plan. Agree as a family that you are going to try the first and if that does not work out, you will try the second.
4. Try whatever it was that you selected.
5. After a few weeks evaluate it.
Did it work? If not then try the back up plan or go back to number 2 and either brainstorm more solutions or try another one.
