When preparing a scene you should ask questions.
The answers aren’t the point; the point is the ‘asking of the questions’ and getting your mind active. The questions will stimulate your imagination, which is one of the best fuels to keep your confidence fired.
Any new idea that you conjure while preparing will always be with you, and that is gold.
Work well and work properly, so that your practice gives on to good habits.
Treat your mind with respect and know it is both powerful and delicate. Simply put: be nice to it.
Asking questions should be a warm and friendly stroking of the mind, getting its best juices going, getting you going.
Proper practice in acting class will help this training.
