In reality, a great dessert can help to complete a successful meal. A bad dessert leaves a sour taste in your mouth that can ruin the whole dining experience. In the context of training, the dessert relates to how we close. We want them to have something to savour from the experience that, like a multi-course meal, brings everything together. For many years, I have preached about the virtues of a powerful close through my trainer training programs. Good training closes, bad training ends. You owe it to your participants to finish the session with impact.
