" If a misfortune has already occurred, it is best not to worry about it, so we do not add fuel to the problem. Don't ally yourself with past events by lingering on them and exaggerating them. Let the past take care of itself, and transport yourself to the present while taking whatever measures are necessary to ensure that such a misfortune never occurs again, now or in the future. "
