I've read quite a lot about things like aliens controlling the earth, the Frequency Fence (which never happened) and so on and so forth. I admit I did't read everything that is out there on all this stuff. But I have always thought that one can make their own world. Though it is very difficult and impossible for some people. But if you know how, I think it might be possible to create your own world the way you want it. I've heard this can be done too.
I think more importantly, it's best to find the right balance that helps one not just survive, but enjoy life, with as little of trouble as they possibly can control. Sure things happen, and we all have challenges. But I think it's not a question of "this could have been or can be prevented". I think it would all happen anyway. It's more like all sentient beings are always changing, and new sentient beings are always introduced into different areas and societies of currently existing sentient beings. And things do change. Even people change during the course of a lifetime.
It's a matter of finding the way to live that you want to live. And thinking seriously about it. I mean, some things you might THINK you want, but when you really think it over, they might not be that great for you anyway. Only YOU can know. I don't think may take the time out of their busy lives to really sit down and think about what type of life they'd like to live, or think about it realistically within their own capabilities and resources. Think about what you have, what you want and how to obtain it. If something is out of reach, think of a way to get around it or try another type of lifestyle that you can obtain the resources to achieve.
What others do then is irrelevant. As long as you are enjoying life.

Realistic life planning and review sometimes can give you what you'd like. If one's happy with their life, outside world challenges will be a bit (or maybe even a lot) easier to withstand, no matter what they are.
This is often hard to understand. I even forget quite frequently!

But I don't really care what the world does, I care what effect *I* have on the world and how I can make it better, and what type of life I'd like to live and how to attain it.
Goals. "Keep your mind on the donut and not on the hole" my dad always told me. Don't worry about the other guys. And if something gets in your path, take care of it the best you can. Enjoy life first.

Now if I can remind myself of this anytime sh-- happens, I too would be all set. [
