Washington, Dec 2 After making a remarkable comeback, pop star Britney Spears says she has planned many things for 2009.

In the January issue of Glamour magazine, the 'Toxic' singer has revealed what positive changes she's going to make in her life.

"I would like to stop worrying so much because I worry all the time," Insider quoted her, as telling the mag.

"And to learn how to be happier, just in general. I have to learn to take things not so seriously," she added.

Spears also revealed what role her new album played in turning things around.

"Recording this album has helped take my mind off certain things. For me, my music is therapy," she said. (ANI)
