Why does Marcus Aurelius’s Meditations speak to us so? The answer, ironically, is that because the author had zero intention of doing so—in fact, he probably would have been mortified to know how well the book has been received...because it meant the exposure of his private thoughts and fears and strugglesAs Ernest Renan observed, Marcus was writing for an audience of one. “Never,” Renan said, “has one written more simply for himself, for the sole end of emptying his heart, with no other witness than God.” That’s what journaling is about. Getting the thoughts out of our head, the anguish out of our hearts, and onto the page. It’s a way of clarifying and alleviating, excising and exercising. For centuries—nay, millennia—people have been pouring themselves into private journals. Some did it at night. Some did it in the morning. Some did it in sporadic bursts or on rare occasion. But in literally countless cases, journaling has been a source of relief and self-guidance. Which is why you should strongly consider picking up the habit this year. Do it on your phone. Do it on scrap paper. Do it in a free notebook you were given in the swagbag at a conference. Or—if we may so humbly recommend it—check out The Daily Stoic Journal, which provides daily prompts and over 20,000 words of Stoic wisdom. Just as Marcus developed this daily habit, so can you. As Musonius Rufus, teacher to Epictetus, said: habit always beats theory for it’s where “one brings together sound teaching with sound conduct.”Whatever method you go with, just go with it. Give yourself quiet time where you can write simply for yourself, with no witness over your shoulder or hovering in the clouds above. Empty out your heart. Clear the racing thoughts of your mind. Leave a record of what you’re learning and what you’ve done. Practice becoming a better human.It will be the best decision you make this year.
