If you had 24 hours to live, what would you do? ‘Memento Mori’ in Latin is a reminder that we will die. In his Meditations—essentially his own private journal, Marcus Aurelius wrote that “You could leave life right now. Let that determine what you do and say and think.” Knowing that this is true, live every day as if it were your last. That means be kind to the people you come across, love as much as possible, give your best to anything you do today. Try this for 24 hours and watch your life change.
