There is some stuff that we love to read, and then there is some stuff that we have to read: to remain relevant in our clinical practice, to be responsible citizens, to be who we want to be. The Journal of Current Glaucoma Practice, Journal of Glaucoma, Survey of Ophthalmology, American Journal of Ophthalmology, British Journal of Ophthalmology, Annals of Ophthalmology, National Geographic, New York Times, Guardian, Times of India, Leo Tolstoy, Harry Potter, Orson Scott Card, Calvin and Hobbes, Vogue… The list is not half complete, we have not mentioned even one of the zillion prescribed textbooks, and we already have three hundred hours of reading, to be crammed into a twenty-four hour day, if we read every day. A twenty-four hour day that also needs us to work, sleep, and go about the general business of living.

We would like to acknowledge the efforts of all our authors and contributors. Without their continued support and dedication, this book would not have been possible.
