For me, coexisting with Barack’s strong sense of purpose—sleeping in the same bed with it, sitting at the breakfast table with it—was something to which I had to adjust, not because he flaunted it, exactly, but because it was so alive. In the presence of his certainty, his notion that he could make some sort of difference in the world, I couldn’t help but feel a little bit lost by comparison. His sense of purpose seemed like an unwitting challenge to my own.
