Make that no matter what is likely to happen. Devolving into a 1984-type total dictatorship would pretty much ruin the rest of my life, but that s unlikely to happen. Being vaporized in a terrorist nuclear explosion would not do anyone much good for their outlook, and do little for survivors either. But that, too, is not likely.
That being said, those things which ARE lklely to occur in the coming years, such as high inflation coupled with high unemployment, China taking the lead as the world's largest economy, Earth's mean temperature going up another 0.5 degrees, gasoline becoming rationed, etc. etc. etc; will unlikely ruin the lives of most - even those affected by a run away unemployment rate.
I tell my children and grandchildren the same thing my grandfather told me repeatedly: Be grateful for what you have, instead of sad about what you don't have. Because there will always be things you want you cannot have. If that is what you concentrate on, you will never allow yourself to be happy.
