“How should we grieve when someone close to us dies? Should we wail and gnash our teeth? Should we swallow our pain? Some would say there is no right answer. You feel whatever you feel, and heal however you heal, and that’s okay. But according to the ancient Stoics – those Greco-Roman philosophers making a comeback as preachers of practical wisdom in a self-help world – there is a correct answer to the question of how we should grieve. And the answer is that we shouldn’t. What’s done is done. There is nothing you can do to change the situation – so move on.”
