(1) Below rules apply to each and every kind of problem
and can be applied in all areas, such as
science, arts, personal life, and politics.
(2) For every problem, there is a solution.
(3) There is only one best solution, the perfect solution.
(4) The perfect solution will be relatively simple and easy.
(5) If a solution is not simple, it is imperfect,
as it hasn't solved the problem
of being (too) complicated.
(6) If a solution is not easy, it is imperfect,
as it hasn't solved the problem
of being (too) hard.
(7) A solution is simple enough when it is understood
by those who need to apply it.
(Relative simplicity is not absolute simplicity.
The solution must be communicated
in a manner and form that is understood
by the target, be it in words and/or pictures,
formulas, signals, programming code, or other.)
(8) A solution is easy enough when it comes as a recipe
that leads those who need to apply it
step by step from the resources they have
to the resources they need for the solution.
(Relative ease is not absolute ease.
The application may take any amount of time,
energy and resources, yet just never in excess.)
