As humans, it's best to focus on what you can control, which is limited to yourself. The world is not something any human being can control, individually or collectively. We can mitigate and delay the inevitable, but we possess no power beyond ourselves to control the world, merely influence others we share it with. That's how propaganda and advertising works, oddly enough. In the end we are only men, we do what we can. Find a good woman who wants to be a wife, you as her husband, and raise a modest, loved, and well nurtured family. Have as many children as you both can raise well. Teach your children to not just be smart, but to be strong. Share the wisdom and insights you gain with your community so others can do the same.
