I like to smile. I smile even when I'm nervous since it calms me down and shows my friendliness.
A good motto is: use friendliness but do not use your friends.
I don't mean being famous is a perk because one knows that it's not necessarily a perk but there are certain perks to being well-known and respected in one's field. Public perks. Like I don't know general friendliness and willingness to please just to point out two.
I've always felt in all my books that there's a deep decency in the American people and a native intelligence - providing they have the facts providing they have the information.
