Common Sense is a quality that must be developed if it is to be utilized to the full of its practical value. Indispensable to this development are such qualifications--(1) Ability to grasp situations; (2) Ability to concentrate the mind; (3) Keenness of perception; (4) Exercise of the reasoning power; (5) Power of approximation; (6) Calmness; (7) Self-control, etc. Once mastered, these qualifications enable one to reap the reward of a fine and an exalted sense, and of a practical common sense which sees things as they are and does things as they should be done.
