Discipline has been defined as a system of techniques of dealing constructively with the pain of problem-solving - instead of avoiding that pain - in such a way that all of life's problems can be solved. Four basic techniques have been distinguished and elaborated: delaying gratification, assumption of responsibility, dedication to the truth or reality, and balancing. Discipline is a system of techniques, because these techniques are very much interrelated. In a single act one may utilize two, three, ore even all of the techniques at the same time and in such a way that they may be distinguishable from each other.
