The emphasis shifts then from the reality of here and now to a wishful fantasy of what might be. But the only life we know is here. And the only influence we have on any life hereafter is through how we live today.
So the point is, that every time has it’s own glamour, it’s own charm. Instead of using that time in regret or spending that time with memories of the past, we should embrace the time we are currently living in.
