" A man of adequate vitality and zest will surmount all misfortunes by the emergence after each blow of an interest in life and the world which cannot be narrowed down so much as to make one loss fatal. To be defeated by one loss or even by several is not something to be admired as a proof of sensibility, but something to be deplored as a failure in vitality. All our affections are at the mercy of death, which may strike down those whom we love at any moment. It is therefore necessary that our lives should not have that narrow intensity which puts the whole meaning and purpose of our life at the mercy of accident. "

― Bertrand Russell
