Help: Translating Napoleon

[cmacq]

My French is very bad.

'The most important quality of a commander in chief is a calm demeanor which entertains substance with an exacting sense. He can not be overwhelmed by good news nor laid low by negativity. Successive or simultaneous emotions perceived over the course of a day must be cataloged in his memory so each may be revisited only in a setting reserved for themselves; as interpretation and appreciation of facts result from a precise contrast of the various effects they evoke. There are men who make a singular picture of events according to their morals and physic; also, in spite of their knowledge, their ability, their courage, and all their other skills, they are not called to command armies, nor direct great military operations.’

I hope this helps?
