I started to realize that everyone goes through those doubts, and I need to try and be the best version of me I can - not only for myself but everyone around me.

Believing in myself has always been hard. For a long time, I constantly compared myself to others, and it took away from the energy I could have been putting into my career.

I am only capable of what I allow myself to believe I can do.

Meeting Justin Bieber was interesting. We were backstage at The Voice, and he was there premiering his "Boyfriend" music video. I was in six-inch heels, so I was towering over him like a giant.

We are so hard on ourselves, it is unbelievable sometimes. The things we say to ourselves or think about when we look in the mirror are so cruel. We have to look at the power we do have and use it to overcome that voice of insecurity.

There is an energy in New York that is like nowhere else I've been, and I feel free there, and that is inspiring.

Making excuses and not trying because I was scared were my go-to reactions. Nothing was going to change in my life unless I did something about it.
