A bit more Amy?
It matters a good deal that your book-food should be strong meat. We are what we think about. Think about trivial things or weak things and somehow one loses fibre and becomes flabby in spirit. Soldiers need to be strong.
Soldiers have not time for everything. ‘I have no time for anything outside my profession,’ a young officer said once, and in measure that is true. We can’t be entangled in the affairs of this life if we are to be real soldiers. By its affairs I mean its chatter and its ways of thinking and deciding questions, its whole aspect and trend. emphasis mine
Am I filling my time with weak or trivial things? Am I spending precious moments on things “outside my profession?” Most of all, am I caught up — in any way, on any subject — with the world’s way of thinking, its trends, its chatter?
