I didn't feel the need for anonymous affection, for people in the dark applauding. To me, it would be like writing a novel and then getting up every night and reading your novel.
Good acting is all in the writing. If it isn't on the page, then it really won't make any difference. You cannot act on force of personality alone.
Commercial jobs are pretty easily adjustable because they only take a few hours to complete, which is one of the reasons they are a Godsend to the actor.
