Other thoughts on acting / language...

Sometimes acting teachers will repeat the same ideas in different words, other times acting teachers will have unique ideas that may seem to come from left field and never to be repeated by anyone else.

"In Shakespeare, never stress the negative."
"But is the most important word in Shakespeare."
"Never sing Sondheim in an audition."
"Never mime objects in an audition."
"Never yell in an audition."
"Always wear your heaviest shoes in rehearsals."
"If you ever say 'oh, God' your character is always directly addressing God personally."
"Any time you have a list, just say it as one long German word."
"Whenever you are acting, never walk on the line.  Plant yourself while speaking."
"Don't speak unless you have the eye-contact of the person you are speaking to."
"The soles of your feat are the key to your body as an instrument."
"We want to see the actor on stage as much as the character."
"Every motivation you have will be caused by love."

Make a list of these off-beat "rules" and file them away, whether or not you like them.  These rules will eventually start to contradict each other (I had one Tony-Award-Winning director tell me never to make eye contact with the person to whom I was speaking) and some of them will even seem ridiculous (an acting coach I once had told me never to wear purple in rehearsal) but if they are important enough for one person to hold as a tenant, there's likely some amount of worth in them...maybe not today, maybe not tomorrow, but soon...and once you figure it out it will serve you for the rest of your life.
