How would I know. If we just try better. Every day. We know what is best. And yet. We do the things we all know lead down the path of 'not a better place'. Don't eat the planet. Don't eat animals unnecessarily. Respect opinions, choices, people. People are different. Celebrate it, don't envy it. Expect nothing.
Schools should teach you have a whole life to learn. School is the basic. And then you learn. Explore. Discover. Change path. Return to your initial path. Abandon all paths from before. Schools should be creative, like life is. Schools should be flexible, as societies expect us to be.
