When making a speech, do not begin stories with lines like "I was ironing my shirt this morning and..." because then the only thing people will be paying attention to is how many wrinkles you have in your shirt and the only thing they will be pondering is whether you are good at ironing or not.
In a play you have to remember that what the audience is seeing are the most joyous or the most heartbreaking moments in a person's life. It doesn't matter if the person is doing something as mundane as eating cereal in a scene, eventually their heart will be full or broken.
In a play, and often in life, the only things worth fighting for are love and recognition. When you are acting you must have an end goal as a character and you must be fighting for something and it will be, in one form or another, for love or recognition. This is so interesting.
Map out a character's goal and actions and then throw it away and only know your goal. That is what we do in life. We only know our goal, perhaps we map out a few actions but Life doesn't usually follow the script we would like. You change your actions to meet your goal. The same with acting, just listen and respond after you have examined your goal.
In a scene we see some of life's most beautiful moments and we are witness to it. But life's most glorious moments usually only happen between one or two people. That is truly wonderful. And only glorious moments happen in real life.
It seems to me that we must all know all feelings. Although we have not experienced all of life's setbacks or joys, we have the ability to know and rejoice or cry with the characters. We, perhaps, cannot know it fully, only dimly, but we know it.
