For many of the exercises, precise instructions are vital: changing a single word can completely derail what was intended, creating either a new version of the exercise or completely ruining it. That is why it is so important that the whole team should follow the giving of instructions and react as needed to prevent misunderstandings. Another good way to avoid misunderstandings is to prepare and check the instructions with another member of the team. Writing down the main points or sentences from the instructions is a common way to insure ourselves against omissions. It is almost always better to read out prepared instructions and to have the exercise plan in front of you. If you notice a drop in your concentration and do not feel confident about running the exercise, it is better to hand it over to someone else on the team than to push yourself into a situation where you don’t feel confident.
