Just as in my investment strategy, I never put all of my eggs in one basket, but diversify and have a back up plan. I also do not go on ships that don’t have some kind of functioning lifeboats and safety jackets aboard, too. That is just plain common sense.
One never really knows what lies in the heart of another. That is why when marrying, or choosing someone for President, do lots of research. Then commend yourself to God and commit.
Really, that is all one can do.
