An amazing insight to any moral or value a person claims...it is something that becomes stronger and truer with practice. Not something you wait to use at the right or special moment.
"Courage, I seemed to think, comes to us in finite quantities, like an inheritance, and by being frugal and stashing it away and letting it earn interest, we steadily increase our moral capital in preparation for that day when the account must be drawn down. It was a comforting theory. It dispensed with all those bothersome little acts of daily courage; it offered hope and grace to the repetitive coward; it justified the past while amortizing the future." The Things They Carried, by Tim O'Brien
