If a segment of one's force is located where it is not sufficiently busy with the enemy, or if the troops are on the march - that is, idle - while the enemy is fighting, then these forces are being managed uneconomically. In this sense they are being wasted, which is even worse than using them inappropriately.

When I look back on my childhood I wonder how I survived at all. It was, of course, a miserable childhood: the happy childhood is hardly worth your while. Worse than the ordinary miserable childhood is the miserable Irish childhood, and worse yet is the miserable Irish Catholic childhood.
Frank McCourt
