Life Lessons From Sex and the City

Her story: Sam is comfortable in her own skin — over 45, single, no children. She runs her own PR company and goes after the clients (and the men) she wants. She's always been aggressive and confident. In one of her gutsiest career moves, she marches into Richard Wright's office and delivers the kind of speech that proves she isn't afraid of anyone or any challenge — and she gets the job.

The lesson: Samantha shows us that the whole being-a-woman-in-a-man's-world thing just doesn't fly anymore. Proof that if you really want something, you go and get it.
