For life is so short and our memories in general so defective, that we ought to seek instruction only from the purest sources.

None but men endowed by Nature with the military mind and trained in the school of the great Captains, are able to write intelligently on the acts and motives of generals of the first order. All the writings of mere literati relative to these uncommon men, no matter how excellent such authors may be, never can rise to anything more than elegant phraseology.

It is of enlightened critics, such as the former, that the youthful student always is first in need. Such will guide him along a road, in which he who has no conductor may easily lose himself. They will correct his blunders considerately, recollecting that should these be ridiculed or treated with severity, talent might be stifled which might hereafter bloom to perfection.

It is a difficult matter to form the average student, and to impart to him that degree of intelligent audacity and confident prudence which is requisite for the proper practice of the Art of Strategetics.

To secure proficiency, the student from the beginning must cheerfully submit himself to a mental discipline, which properly may be termed severe; in order to make his faculties obedient to his will.

Secondly, he must regularly exercise these faculties, in order to make them active and to acquire the habit of implicitly conforming to the laws of the Art; to make himself familiar with its processes, and to establish in his mind that confidence in its practice which can come only through experience.

The student daily should exercise his mind in the routine of deployments, developments, evolutions, manoeuvres, and operations, both on the offensive and on the defensive. These exercises should be imprinted on the memory by closely reviewing the lesson of the previous day.

Even with all this severe and constant effort, time is necessary for practical tactics to become habitual; for the student must become so familiar with these movements and formations that he can execute them instantly and with precision.

To acquire this degree of perfection, much study is necessary; it is a mistake to think otherwise. But this study is its own sufficient reward, for the student soon will find that it has extended his ideas, and that he is beginning to think in the GREAT.
