The word theatre comes from the Greeks. It means the seeing place.
Life beats down and crushes the soul and art reminds you that you have one.
The theatre is a spiritual and social X-ray of its time.
Your curse is that you have chosen a form that requires endless study .... It means you have to read, you have to observe, you have to think, so that when you turn your imagination on, it has the fuel to do its job.
You have to get beyond your own precious inner experiences.
When you stand on the stage you must have a sense that you are addressing the whole world, and that what you say is so important the whole world must listen.
