This work has been written in honor of all the patients and their families that have blessed me with their faith, unconditional love of each other, and courage. This work is devoted to all students, the clinicians of tomorrow, to whom I wish the joy of spending their professional days steeped in the continual pursuit of knowledge, relentless inquiry, deep caring, and the wisdom of gratefully knowing that you always receive twice as much as you give. You have all touched me forever and given me more blessings than I can ever count.
