Before negotiating a raise, you need to understand one thing, says supermodel and entrepreneur Emme: How much you're worth.
If you're worth more than what you're currently being paid, shop around for other positions, Emme encourages. "While you have a job, start looking for another one — and when you get a really good job offer, go back to the job that you have … and let them have the opportunity to pay you more. Then you have a decision to make: Do you want to stay or do you want to go?"
She's not the only successful businessperson whose advice emphasizes first understanding what you're really worth.
