having high standards only makes people more satisfied if they’re in strong marriages—and having lower standards is better for marriages that aren’t as secure. [snip]

Anyway, one doesn't need science, just a bit of Reinhold Niebuhr:
God, give us grace to accept with serenity
the things that cannot be changed,
Courage to change the things
which should be changed,
and the Wisdom to distinguish
the one from the other.
