What is a difficult problem?

One that has a difficult solution.

Let's see:
  - simple problem: a solution is clear intuitively at a glance
  - complex problem: a factoring into simple problems is known
  - intractable problem: no factoring is known

How to become an expert?

  * Know the simple solutions of your domain.

  * Don't build unnecessary complex solution through ill-informed
    decomposition.

  * Build more intuitive understanding of composite solutions by
    familiarizing the ``inbetween space''.

  * Recognize the smell of intractability.
