Great individuals 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. As it turns out, this is one thing all great men and women of history have in common. Like oxygen to a fire, obstacles became fuel for the blaze that was their ambition. Nothing could stop them, they were (and continue to be) impossible to discourage or contain. Every impediment only served to make the inferno within them burn with greater ferocity. These were people who flipped their obstacles upside down. Who lived the words of Marcus Aurelius and followed a group which Cicero called the only “real philosophers”—the ancient Stoics—even if they’d never read them. They had the ability to see obstacles for what they were, the ingenuity to tackle them, and the will to endure a world mostly beyond their comprehension and control.
