I specifically didn't argue that. Would you spurn wisdom because it might not apply to some people who read it? Your call, but I wouldn't understand it. Would it be easier if we just put out a browser extension that stamped "I don't know who needs to hear this, but..." in front of every piece of advice? Couldn't you just imagine it being there instead?..so you don't miss out on what might apply to you by wasting your time thinking about who it doesn't apply to?
