A sexual athlete is not likely to find sufficient energy for work of another athletic kind, and the acting of great parts most definitely was and always will be athletic, depending on inner if not on visible energy. Members of other professions that depend on the expenditure of physical energy must, I believe, find similar difficulties when attempting to double up on their energies. One has often heard that the most magnificent specimens of boxers, wrestlers and champions in almost every branch of athletic sport prove to be disappointing upon the removal of that revered jockstrap.

You think you're an artist; prove it

We ape, we mimic, we mock. We act.

Have a very good reason for everything you do.

I have to act to live.

There is a spirit in us that makes our brass to blare and our cymbals crash-all, of course, supported by the practicalities of trained lung power, throat, heart, guts.

Shakespeare - The nearest thing in incarnation to the eye of God.
