The Royals singer has already started penning ideas for the follow up to her huge debut album, Pure Heroine, which was only released in September last year.
She told Billboard magazine: "I'm definitely writing new stuff. I don't know how everything willend up. The first period of writing after you have recorded an album, it all sounds like the album before it.
"I'm trying to get that out of my system and move it to a new place. But I've been writing with some good people and just doing weird, cool stuff - which is always good for being creative."
The 17-year-old star also said while she has already achieved a great number of her personal goals with her career, her success has also enabled her to approach her music and performance in a different way.
She added: "I feel like I've achieved a really healthy amount based on how much life experience I have. In terms of being creative, based on a really small amount of time being old enough to have experiences and think about stuff, it's only been a couple of years in the scheme of things. So I feel like with that in mind I'm doing well.
"I think now when I'm doing stuff I think much more about a project as a whole. I try to make every little part really strong - like the live show, which I've been pouring my heart and soul into right now and just making it like the inside of my brain on the stage. Before I would just kind of do something.
"Now I am super methodically planning everything and making sure everything links up and how that will tie into the next album and the album after that. I'm looking at the big picture much more."
