More good reading

I am reading The Blessing of a Skinned Knee (thanks, Deb) and it is incredibly insightful and full of wonderful ideas to ponder as you aim to raise a happy, well-adjusted, healthy child. The chapters cover a wide variety of topics and basically shares that most of the parents today are struggling for a variety of reasons, but one of the chapters is dedicated to bringing out your child's strengths by re-channeling the things that make you moderately insane. But, there are so many things that a typical two-year old does that can drive you up a wall, my question is: how do I determine that one thing?
