If You Could Make One Law That Everyone Had to Follow, What Would It Be?

If you could make one law that everyone had to follow, what would it be? This is a good example of a second conditional quest. We're using the second condition ar not not the first conditional, because it's unlikely to happen. I've been thinking about this myself. One idea that i had was, what if everyone in school went through kind of meditation classes? I feel like it could stop a lot of violence and misunderstandings in the world. Butit may be, you might think i'm giving too much importance to the power of meditation, but i feel that that could be a good law too, in force asBut let me know what you think.
