When you’re a child, the minutes seem like hours and the hours like days.
Then, you grow up. And time flies.
Despite the fleetingness of time, if you’re like most people, at some point in your life you’ve “killed time.” Perhaps you’ve even killed a whole day. Or days. “Killed ’em dead.”
What is a dead day? It’s a day without good deeds and mitzvos. And what’s an alive day, a day brimming with vitality? It’s a day packed with good deeds and mitzvos.
Good deeds include acts of kindness as well as acts of duty. Good deeds are driven by the heart.
