Scarlett Johansson thinks ambition help people to unleash their talent and be successful. The Hollywood siren claims that having high objectives is healthy. "Ambition is healthy. All people who are successful are ambitious. And you have to be ambitious to be successful. And you have to set goals for yourself. I think that's important," the Age.com.au quoted Johansson, as saying. Meanwhile, Scarlett is gearing up for the release of her music album “Anywhere I lay my head,” scheduled for May.
