The points that struck me and made me say "ah ha!" were the point of boys being action-oriented, and the explanation of why boys focus on one thing and why girls can tell you every detail of their day.
I wondered about the idea that girls can change focus quicker than boys (e.g. boys playing Wii "ignoring" mom standing by him and calling his name). Even older boys have this problem - is that a "holdover" problem from something not developing correctly, or just the nature of all boys and men?
"When we don't intentionally channel and guide our boys aggression, independence, tension, ambition, assertiveness, and competitiveness, we do them a great disservice." I love this idea, and I think it's the reason a lot of boys are so lost when they become men.
Of the mistakes they listed, verbal flooding is the one I tend to make. My son's only 2 1/2, so I generally give him short commands, but I teach a class of seven 5-10 year old boys each week, and I tend to overwhelm them with words. I'm a teacher by personality, and I want to explain everything. As my DS gets older, I know I'll lean toward doing this with him.
