I tried to go anorexic for a good three hours. I ate ice and celery, but that’s not even anorexic. And I quit. I was like, 'Ma, can you make me a sandwich? Like, immediately.'

I didn't know fashion or any of that until the label gave me a stylist.

I want to be better at being single, and I want to be better at feeling okay about being single. I don't need a boyfriend.

When I got famous, all of a sudden guys wouldn't look at me. Period. So I felt a little sad, a little frustrated. Like, What's going on here? I've never been prettier in my life and I'm so cool and successful.

It still hasn't kicked in yet. I haven't had a second to think about it. And I don't physically have the Grammy! So I can't even look at it!

As the CEO running my life, running Meghan Trainor, I have to say 'no' to things all the time, and it's been very uncomfortable and very difficult. I've said 'no' and it's actually worked - even when I never thought it would work.

There's a lot of power in the word 'no,' and a lot of people, like myself, need to know that.
