I reference the 'Cutting the Gordian Knot' section in the Pragmatic Programmer[0] when dealing with tough problems.

Cutting the Gordian Knot [1] When solving impossible problems, ask yourself:

* Is there an easier way?

* Am I solving the right problem?

* Why is this a problem?

* What makes it hard?

* Do I have to do it this way?

* Does it have to be done at all?
