The trick is not to squash the essence of boys, but to channel their natural wildness into manliness. And this is what keeps me awake at night, because it’s going to take a miracle for someone like me, who grew up without meaningful male influence, who would be an embarrassment to Teddy Roosevelt, to raise three men. Along with learning what makes a good father, I face an added dilemma: How do I raise my sons to be better than their father? . . . As I stumble and sometimes fail, as I feign an interest in camping and construction and bugs, I become something better than I was.
