The two sides of yourself: your public persona and your private persona: need to be kept separate today. And make that separation stick. No fine lines, here! The people who want you to mix the two halves of your life together don't necessarily have your best interests at heart. They aren't necessarily thinking selfishly, but they are probably thinking senselessly. Maybe they can meld their two halves together seamlessly, but you can't: and you shouldn't try to mimic them.
