I would like to thank my friends and family for being there for me as support for both my troubles and triumphs. Without their encouragement, I would not have finished this book or achieved any of the other things in my life that make me proud. An especially big thanks to my parents, Fern and Joe, for continually providing me with the tools I need to do the things I love.
