ON ACTING: How to Avoid Doing Nothing
One corrective is an attitude shift: accept that nothing is ever perfect. Even the universe is not in its final form.
Consider everything you are working on (including you) to be a preliminary draft, a work-in-progress...even if certain drafts have to be turned in and given hypothetical final forms...like a published book or a written movie script or a stage performance. But even then, notice: books are revised, scripts are re-written (even their movies have re-makes) and there is always tomorrow night's performance; or another 'take' if we are doing film. Yesterday's work was just a prelude to today, today's work is just a prelude to tomorrow; and tomorrow's work a prelude to the day after that.
Wake up every day and work a little more on your continuing imperfect work of art; make it better knowing it will never be "best."
Think of perfection as death, the end of growing. The joy of life--and art--is in the process, not the final result (especially if, once again, we think as the final result is death: "His life is perfect now...he's in the grave.")
I suggest: "I'm happy again...back at work! Will my work ever be perfect? Of course not. But I'm perfectly happy just being back at work."
