Michael Caine, the English actor, observed “The difference between a movie star and a movie actor is this – a movie star will say, ‘How can I change the script to suit me?’ and a movie actor will say,’How can I change me to suit the script?”

Its not just actors though, it it? There are people who go though life with the attitude of an actor, and there are those who think more like a prima donna, expecting things to happen the way they want them to.

Guess who is the happier, and the more popular?

The curious thing is these apparently self-centred qualities can actually make you more successful at getting what you want, because popular people also tend to be more influential.

Not a lot of people know that.
