The rider should sometimes act 'as if' spectators are watching both him/her and the horse.
This offers several advantages:
- If one day there is a real audience, you are mentally prepared.
- You will train seriously and concentrated.
- If you also 'internally' explain to the 'imagined' audience what, why and how you are doing what you are doing, you will find out 'gaps' in your knowledge or you will find out that you perfectly know what you are doing.
