When a solution arises out of the problem itself, the problem disappears. 

It is self-sustaining because the solution is the new state of affairs.

When you work through both the external and internal
challenges to a situation, problems do point to their own
solution. You see that all you need to do is implement what
needs to be done and you have developed the tools
and skills that enable you to do just that.

When you implement solutions this way,the solution is
self-sustaining. The pieces you have put in place,
internally and externally, reinforce each other to create
robust and effective strategies that you can apply in a
variety of contexts.

And you are able to show others how to apply
these methods to the situations they encounter
in their own work.
