第2章 Acknowledgments

Thanks to the key Schwartzbergs in my life—my wife Anne; my kids Evan, Mylie, and Josie; and my parents Howard and Susan—for their unconditional love and support.

Also thanks to the crack team at Berrett-Koehler, especially Neal Maillet and Jeevan Sivasubramaniam for their encouragement and expert guidance.

If you can't explain it simply, you don't understand it well enough.
