"On a dark night at the front in the year 170 Marcus Aurelius, the most powerful man in the world, wrote the following prescription to himself: 'The impediment to action advances action. What stands in the way becomes the way.' Great individuals, like great companies, find a way to transform weakness into strength. It's a rather amazing and even touching feat. They took what should have held them back—what in fact might be holding you back right this very second—and used it to move forward. Like these great individuals we can also flip our obstacles and turn adversity into advantage."
