Young people do not necessarily view uncertainty in their lives as negative, especially those most-marginalised youth who see their &8216;certainty&8217; as poverty, unemployment and environmental fragility. Youth perspectives presented in this book show how some of the most-marginalised youth seek &8216;positive uncertainty&8217; by escape from traditional practices and social bonds in families and communities, through migration or seeking innovative and alternative ways to meet peer, adult and societal expectations.The authors explore how youth see uncertainty in their lives as they grow up in different parts of the world, and how they respond and take action in terms of positive uncertainty&8217;. When young people don&8217;t know what is going to happen in their lives and contexts, they often embrace it as positive and use their creativity to take up new opportunities and futures.
