Peace starts with you. Ordinary citizens can make a difference. When’s the last time you said sorry? Think about who loses when you win. Are the people around you heard and respected or marginalized, ignored and left out? Make a decision to care about what happens to them. Start a constructive conversation with someone you disagree with. Challenge ‘them-and-us’ thinking in yourself as well as in others. Every one of us can choose to make society more just and peaceful, or more unjust and warlike.
