ACKNOWLEDGMENTS

I WOULD LIKE TO THANK Adaobi Obi Tulton, Maureen Spears, and Luann Rouff for making this text more readable; Mary James; and Jim Minatel; and everyone else at Wiley who helped to get another edition of this great book published. I would also like to thank my wife and children for supporting my writing. You’re my inspiration.
