…the best way to protect yourself is to maintain a robust distinction between your inner self and your presence online. Remember that at its best, social media is a tool. You ought not let it define you or let it creep into your self-concept. It is inherently dehumanizing, and if you let it in too deep, you will end up dehumanizing yourself.

But social media should be a tool, not your boss and not where you derive your sense of self.
