This paper, first presented to a group of training analysts in 1938, is here published from a mimeographed copy in the San Francisco Institute dated 1942. Gill explains in his preamble that there was a reluctance originally to publish this paper as it was felt that it would not be useful to the public to read about problems that the analyst himself might have in regard to his training. The paper is so full of gems concerning technique and the problems confronting the training analyst that it is suggested that the paper be included in the bibliographies of every institute, to be taught to all advanced candidates. It is particularly important to note that although Fenichel focuses specifically on problems that occur in the didactic analysis, many of these apply equally to any analysis. One of the most important points that Fenichel makes is the frequently forgotten recommendation that the candidate should have a "deep and thorough training analysis."
