answer:It’s a wonderful thing to enjoy the place where you work. I am very lucky that I enjoy mine as well. My department is very collegial, which is unusual for a PhD program. Ever since my first year, more advanced students have been very helpful and welcoming, and I keep trying to pay it forward with the students who came in after me. Also, my adviser/boss/mentor is WONDERFUL, and everyone loves him. I am so lucky to be working with him.
