"The first thing to do to become happier, paradoxically, is to accept painful emotions, to accept them as a part of being alive. You know, there are two kinds of people who don’t experience painful emotions such as anxiety or disappointment, sadness, envy; two kinds of people who don’t experience these painful emotions. They are the psychopaths and the dead. So if we experience painful emotions at time, it’s actually a good sign. It means that we’re not a psychopath and we’re alive. The paradox is that when we give ourselves the permission to be human, the permission to experience the full gamut of human emotion. We open ourselves up to positive emotions as well,"
