A responsible attitude is important, i.e. that a mistake or oversight is not the result of neglectfulness. Therefore, if there is fear, it is a concern that comes out of a sense of responsibility. You can’t turn it off – it would probably not be good if it was completely absent – but you also shouldn’t be too hard on yourself even if you make a mistake, because we are all part of the learning process, even when we are the ones running the training. A safe space within the team to openly discuss difficulties, as well as transparency towards the group about the difficulties that arise, can go a long way to helping build and maintain self-confidence, i.e. deconstructing fear.
