"I just knew it was my time. I knew I wanted to do something different and start expressing the way I felt about certain things.
"I know that musicians are seen as one-sided people a lot of the time. But we do have other elements to us as well. I didn't feel good. Do you know what I mean? And if you don't feel good... You need to be able to express what it is that you are. I'm free at last," Zayn said.
