I dedicate this book to my parents, Virginia and Michael (deceased) Porcari. There is a
book by Robert Fulghum entitled All I Really Need to Know I Learned in Kindergarten:
Uncommon Thoughts on Common Things.I would say that everything I needed to learn
about life I learned at 110 Wheeler Avenue in Orange, Massachusetts...my home. My
parents raised four children and treated us all with selflessness and unequivocal love.
For that, my brother, my two sisters, and I will be forever grateful. —J.P.
To my late parents, Joe and Buelah, who are without question the two people most re-
sponsible for any success I have experienced personally or professionally. I thank them
for instilling in me a love of learning and a commitment to “doing the right things the
right way.” I share any and all accomplishments with them. —C.X.B.
To my parents...the beacons in my life. Words will never convey my gratitude for all you
have given to me. Thank you for your relentless and unwavering support. —F.C.
