Training the Trainers recently

My experiences in training and trainers had been a mixed one.On one hand I encountered the group which were highly receptive with an attitude to unlearn and relearn, whereas on the other there were tribes who thought they were Mr. and Ms. Perfect. To my surprise the latter felt that trainer need to understand the tricks of the trade only once and need not require any updates periodically. Training people on management and soft skills which are my areas calls for an extremely versatile approach with an attitude to learn at every time.Business environment being turbulent and volatile a trainer cannot rest on past learnings, rather he has to upgrade himself with the changing times, which calls for unlearning and relearning which in turn is linked to the attitude of the trainer.A senisble trainer especially the ones in management and soft skills learns new tricks by only being a minute observer, the rest simple follows.
