It is may be a cliche in the acting and entertainment business, but often we forget to just breathe and relax when we are working under pressure. A director can sense when an actor is under pressure and is not himself.
Remember that breathing and staying calm is a top priority and should always be treated as one. Daily meditation can help relieve the stress and anxiety that develop in a highly pressured environment, such as entertainment and acting.
Many people cringe at the thought of reading to themselves or practicing in front of a mirror. The truth is, practicing in front of a mirror helps prepare and guide you through your entire presentation. With repetition and familiarity, the subject becomes well-known, and the fear of the unknown disappears. The nerves begin to dissipate as you work through the issues that would have arrived at a not-so-private time, such as an audition or on stage.
Try creating monologues in different categories, whether humorous, dark or witty. Practice with different people on different subjects to become comfortable with yourself and your own presentation, so you can fix any faults or inconsistencies you don't like.
Record your latest script and lines in your monologue on video. Just like practicing in front of a mirror, recording yourself will allow you to continuously look back and take note of your performances. When you view your recordings, study your personal techniques and decide what you love about your performances, not just the negative. Positive reinforcement will help build your confidence and allow you to perform at your best.
In the entertainment business, you must always keep your chin up. Millions of people aspire to become actors, musicians and entertainers each year. Working in the entertainment business is one of the most cut-throat industries to work in, due to the physical and emotional demand. Understand that criticism and critique is part of the job, and you should never take any negativity personally. Some people, just as in day-to-day life, are unforgivably rude and this industry is no exception. Be prepared to move forward with your own objectives, not anyone else's.
