When I read the title, I was curious: is it about a business setting, or, maybe, about a private relationship / marriage context? As someone, who has walked away from more than one relationship, I see this perfectly applicable and sensible advice in both contexts, really. Thanks.

Being willing (even ready) to walk away from marriage completely defeats the point of about half of the intangible benefits of marriage.

Always being ready to leave a relationship sounds like personality flaw, not sensible advice.
