Many people just obsess instead of preparing a practical plan.
The secret to successful preparation is a complete mind movie of the situation. This movie must include all likely alternative plots and at least one of these plots should have a happy ending. The happy-ending plots are the ones you need to hone in your preparation and rehearsal until they become overwhelmingly more likely than the ones with a sad ending. The key here is to script this conversation realistically until it results in some acceptable agreement. For example, suppose a colleague, Max, has been spreading rumors about you, implying professional incompetence.
