“Don't solve problems, pursue opportunities.”

Context: A few years ago I heard a quotation, and I am going to modify it here: If you think technology can solve your security problems, then you don't understand the problems and you don't understand the technology.

Context: One of my working assumptions which has been proven successful so often as seemingly to qualify it as a reliable tenet is that A problem adequately stated is a problem solved theoretically and immediately, and therefore subsequently to be solved, realistically. Others have probably stated the principle in many ways. The assumption is that the inevitability of a solution's realization is inherent in the interaction of human intellect and the constantly transformative evolution of physical universe. At first the, only subconsciously apprehended, approaching confluences of complex events make themselves known intuitively within the intellectual weather. Then comes a gradually awakening consciousness of the presence of new families of differentiating-out challenging concepts of every day prominence. It is with these randomly patterning families of separate concepts that evolution is about to deal integratively. As a now specific unitary problem it may be disposed of effectively when and if that unified problem becomes "adequately stated" and thereby comprehensibly solvable.
