Tracy Kidder, A Truck Full of Money

Kidder always chooses interesting, even eccentric characters to cover. Paul English, entrepreneur, programmer, person with bipolar, is another one. I did find him intriguing and dynamic. But I think I was expecting more of a story arc for English. I know that when writing biography, one doesn't want to fit life to a pre-set arc. But I lost some interest about halfway through, when the storyline and timeline started getting fuzzy.
