> The good news is that it doesn’t matter if we find we have married the wrong person. Yes, it does! OMG, this so laughably wrong. (The whole article.) Who you marry is a big, big determiner of happiness. It's better to be single than to marry the wrong person.
For some people. The path you like is not necessarily optimal for me.
Many marriages survive on companionship and familiarity.
My great grandparents were married for almost 90 years (Indian arranged kid marriage) and they were both centenarians. They seemed happy enough (but how could I tell as a kid). Maybe some of the things they lived through (e.g. two wars) seemed like bigger deals than the (inevitable) conflicts in their marriage?
