By the way, a clear answer to the question should not exceed one minute more often. It is about 0.5 pages of typewritten text. It is better if even shorter (but exhaustively). If a candidate for a degree at the answer to the question begins to speak for a long time, it seems that he "swam", he is bad that he's talking about. But here you have finished thesis and dissertation on the observations, thoughtful answers to possible questions - at this stage and you have become, in essence, PhD. But most candidates for a degree at this stage appears and more - a sense of insecurity, a feeling of smallness made (and at the beginning of work on the dissertation thought that you turn all the pedagogical science). The author considers it necessary to notify the psychological barrier - pass through it almost all. But then, some time after the successful defense, receiving a diploma, he is replaced for some time on the opposite - some sense of excessive pride, and sometimes, unfortunately, and conceit. But life is life, and we are all humans.
