This book introduces a series of workshops known as the 21st Century Ready workshops specifically crafted for high school and university students. The purpose of these workshops is to motivate and empower these young adult students to be agents of positive societal change by equipping them with the mindset and conceptual tools to tackle the dire global problems of our time. Through these workshops, they will be able to envision the kind of world they want to live in. They will see themselves as important participants in an international community and will recognize and embrace their responsibility as world citizens. In a world buffeted by increasing crises that include climate change, gross human rights atrocities such as genocide, the proliferation of weapons of mass destruction including nuclear weapons, global financial crises, terrorism, the threat of global pandemics, territorial aggression, and shortages of food and water, it is easy for this generation of millennials to feel fearful that the world is spinning out of control. Such fear can lead to despair and apathy which lead to a paralysis of action which our world can ill afford at such a critical time in the fortunes of humanity. The 21st Century Ready workshops will motivate the young participants to take ownership of their destiny and exercise their ability to choose new ways of responding to the challenges of our time. They will find creative, practical, principled, high-impact and highly-effective ways of acting to solve the seemingly insuperable global problems we face. Instead of allowing these global challenges to become stumbling blocks that lead to more suffering, they will find themselves empowered to make choices that can turn these challenges into stepping-stones that lead to a more peaceful world and secure world in which their generation can fulfill their individual and collective potential.
