I can't tell you about acting. You can develop all the skills, voice, gesture, movement, you can develop by exercise and practice but finally fundamentally it's mining from yourself, from your own personality, from what you know. If you can't know it you can have a good guess by people you know or books you've read.
Peter O'TooleMany years ago I sent an old, beloved jacket to a cleaner, the Sycamore Cleaners. It was a leather jacket covered in Guinness and blood and marmalade, one of those jobs... and it came back with a little note pinned to it, and on the note it said, 'It distresses us to return work which is not perfect.' So that will do for me. That can go on my tombstone.
