so yes, some journalists, woodward and bernstein or robert caro, are very good at being tough about their subjects. for me it's a little more difficult and had to push myself. >> why do you find it difficult? >> i came to like the people i write about. whether their contemporary or not. i like steve jobs a lot. i respected him. i admired him but i like ben franklin thought and respected and admired him. so when you having to do the downside or story and a biography that's rough, you kind of flinch a bit because you almost feel like these are your friends so you don't want to say anything unnecessarily harsh about them. i think that makes me less of a good biographer in a way that i tend, you know, to try to find the good light i can use on a particular subject but i know that people read my books, including people within the subjects of the books deal with sometimes i was too harsh. that's what you cut a balance. you try to do it honestly but not just rigorously honestly. he also try to do with a good heart, or i do, which is what we see fight can understand why somebody did it this way e
