Acknowledgments

I personally would like to thank the following people:

• Nancy E. Cropley, R.N. (d. 2002) As a political activist, you fought for what you believed in: social justice, peace, and universal health care. You were never afraid to go to jail to support your beliefs. Your example is helping me find a backbone for life.

  As a nurse for the homeless, you helped so many who are less fortunate. You worked tirelessly in the clinics, in the shelters, and on the streets. Your efforts eased the pain of so many people. And you saved lives. Nancy, you are my hero.

  As an Internet entrepreneur, you showed me how to be happy pursuing a life working from home. You made it possible for me to have the freedom to be, instead of getting stuck in the corporate world.

  Nancy, you were my partner, my lover, my soul mate. You helped me find joy in this world. I take your lessons with me. I hold your spirit in my heart. I thank you for the best seven years of my life.

• All the incredibly hard-working folks at McGraw-Hill/Osborne: Brandon Nordin, Scott Rogers, Gareth Hancock, Tim Green, Jessica Wilson, Jody McKenzie, Lunaea Weatherstone, Susie Elkind, and Jack Lewis for their help in launching a great series and being solid team players.
