There will always be some sort of "bad luck" or "external negative circumstances" or "social circles with a lot of ill faith" in our lives, just like there were bullets during the WW2 war.

Probably the best way forward is to understand what areas are vulnerable to those "negative circumstances", work on them step by step, and learn how to live in such a way that the they won't "crash our plane" next time we bump into each other.

It's a slow, life long process.
