This is my work desk. A usual desk of a grad school student. Do you think that in grad school we get paid to read interesting books? Sometimes we do. We like some books more than others, but the most important part of grad school is to convince yourself that something that you must read (say, it is required for your course work completion) IS really interesting and relevant for you. It is one of the most difficult tasks to acquire. At the end of the day, when all the confusing literature is read and set aside in a neat stack, it feels amazing to fill up a travel mug with some good tea and then open up all these files with biographies and memoirs of mysterious mathematicians.
