As per a classic sutra of Buddha.
If someone shoots you in the foot, don't pick up the bow and shoot yourself in the second foot. Don't make your sufferings worse, in other words, by arguing with what's so. That's a second arrow . Accept pain. Don't criticize yourself, or others, for feeling pain: that is a Second Arrow. Don't regret what cannot be changed, or try to predict what cannot be known..
