Gore Vidal said this quote

I have never been an eavesdropper, even in childhood. Not from any sense of virtue but because I really do not want to know what people think of me or, to be precise, what they say of me - often a different matter. I can usually imagine the unpleasant judgements, for we are what others needs us to be. That is why our reputations change so often and so drastically, reflecting no particular change in us, merely a change in the mood of those who observe us.
