A representative sampling of letters from those of application to the Peace Corps to the aftermath of service giving a valuable, balanced view of the Corps' activities and the participants' experiences. There are comments on training days in Washington; on living abroad (watch out for ""culture shock""); the diary of a teacher's day in Ethiopia and notes on other days elsewhere. As the corpsmen and women reach the two year mark of service, they proffer advice to new colleagues. For the public at large, this offers a genuine understanding of the Corps at a personal level. Introduction by Sargent Shriver.
