Pop superstar Christina Aguilerafeels that she hasn’t achieved enough yet in her already impressive career.

The platinum-selling singer claims that there are still a lot of things that she wants to accomplish before she’s happy.

She told InStyle Magazine: "There are still so many things that I'm yet to accomplish, I think it's something that I do tell myself, just to stay hungry. I am an overachiever and an extreme perfectionist.

“I would like to do more film and I feel that I still have yet to acquire the type of success that I desire. I'm sure there will definitely be a place that I will be at peace with knowing I've accomplished a lot."
