A lot of literature and other stuff comes to all JET participants from the main office and others. I tend to flip through stuff, including essays, articles, photographs, etc.
The one thing I can tell you that I feel every time is intense jealousy. You see while I live a very mundane and decidedly un-Japanese life in the most indescript of places in Japan, others are out participating in local festivals, living the local life, living a life with something meaningful. My featureless section of featureless Saitama often feels like it has absolutely nothing going for it. I get jealous and throw out the materials I receive.
I know it's not precisely like that, but it often feels that way. At these times, I feel sorry for myself and others who were unfortunate enough to be placed here.
