Accordingly, Stoic and Epicurean thinkers spent much time devising techniques and thought experiments. For example: imagine that today is the last day of your life. Are you ready to face death? Imagine, even, that this very moment – now! – is the last moment of your existence. What are you feeling? Do you have regrets? Are there things you wish you had done differently? Are you really alive at this instant, or are you consumed with panic, denial and remorse? This experiment opens your eyes to what is important to you, and reminds you of how time runs constantly through your fingers.
