The biggest mistake was accepting to train theory yet all administration work was to be done by me where by me whereby some times in theory trainings new clients would come for registration and inquiries yet very busy in class hence inconvenience to my theory class for the sake of new customers which used to make me compensate their time and led to inadequate personal time at home because I liked faithful work for the school to be known. Therefore, though I regretted accepting with my boss it made some development inn the school finally hence am advantage.
