Understand: day in and day out, people emit signals that reveal their intentions and deepest desires. If we do not pick them up, it is because we are not paying attention. The reason for this is simple: we are usually locked up in our own worlds, listening to our internal monologues, obsessed with ourselves and with satisfying our own egos. Like William Macnaghten, we tend to see other people merely as reflections of ourselves. To the extent that you can drop your self-interest and see people for who they are, divorced from your desires, you will become more sensitive to their signals.
