Taylor Swift isn't spontaneous enough

She may be perceived as calm and steady, but Taylor Swift says she wants to be viewed as more spontaneous.

The straight-laced hitmaker admits she usually plans her career two years in advance but is trying to learn to be more impulsive and is going to let her story "write itself" for sometime now.

"What I'm looking forward to in 2016 is not knowing what's next. I've always planned my career a year or two in advance, and I refused to do that this time," she reveals.

"1989 was such a huge chapter in my life and career, and it's an exciting thought to let the story write itself now for a while."

The 25-year-old star has had a long year, having toured many countries across the globe as part of her '1989' world tour.

When asked to reflect on 2015, she shared to People magazine: "The most challenging part of the year was being on-point for every show of a huge stadium tour.

"There was a lot to remember and balance with all the surprise guest performances, but it was worth it. I feel like we created memories I'll cherish for the rest of my life."

Meanwhile, Taylor previously admitted she felt "lucky" to be liked by so many people.

She said: "Things are good right now but I'm never going to be stupid, foolish or ignorant enough to think I have control over the public. All I can control is making good music.

"I am so lucky that people seem to like me right now, but in no way, shape or form is it a permanent thing. And I think being aware of that is what keeps you smart and is what keeps you on the game."
