Hmm. I suppose I should clarify that these ideas did not save me in combat, and probably would not save anyone in combat. There isn't a philosophy in this universe that would save you from "Whoops! Should have juked right when I juked left!"... But from other things that can kill you, Stoic philosophy will set you up for survival.
About the question, though, I thought about what he said about telling friends and family you're always busy. It was just something that came to mind, making me wish I'd spent more of my time with people I enjoy being around.
