Be ambitious; find everlasting love; look after your health--there are countless stories about how we ought to live our lives. These narratives can make our lives easier, and they might sometimes make us happier too. But they can also trap us and those around us. Here, happiness expert Professor Paul Dolan draws on a wealth of evidence to bust the common myths about our sources of happiness and shows that there can be many unexpected paths to lasting happiness. Some of these might involve not going into higher education, choosing not to marry, rewarding acts rooted in self-interest and caring a little less about living forever. By freeing ourselves from the myth of the perfect life, we might each find a life worth living.
