- Prepare well. Gather all the relevant details. You must have all the necessary facts, and they must be correct.

- Give sufficient background information, but don’t bore your audience.

- Be prepared to give clear reasons for each suggestion.

18. Play the game “Categories”.

Players guess answers that fit a particular category. When choosing categories, consider the ones connected to your specialty.

The basic rules are simple:

1. Choose a category;

2. Decide on an order that players will answer;

3. Start naming items (in the order decided in Step 2) that fit the category until players can’t name any more.

Repeating an item that has been named is not allowed. Players can decide if they want to put limits on how much time players are given to think of an answer.
