 We were insecure in our schools, in our homes, in our relationships and on social media. And of course, we felt and we still feel insecure about our very selves, about our appearance, our intelligence, our age, our health. Insecurity, of course, is not evenly distributed. Without a doubt, its sharpest edge is reserved for the most disadvantaged and discriminated against, and that's important. But it is still widely felt.
