If we go through life not worrying about what other people think of us, does that mean we don't care? How can one differentiate between the two?
And if no one cared about what other people thought of them, would the world be a better or worse place? Many self-help literature contradicts itself when it says in one breath, "Be yourself, don't worry about other people think of you" - but in the next, "Care about those around you, be sensitive to them and basically 'do unto others as you would have done to you'."
How can these two thoughts be reconciled?
