Being an ambassador is a honour and you should treat that nomination with respect. Ambassadors are responsible not just for themselves but for the entire delegation. Giving a short (1-minute) mandatory opening speech in the opening session of the General Assembly is one of the most visible duties of an ambassador. On rare occasions, ambassadors might be called upon during committee sessions to deliver a speech in a committee different from their own. To prepare for this, ambassadors should acquire a basic knowledge of the issues debated in those committees where the delegation has no representative (including the International Court of Justice).
