Selena Gomez

You might think Wizards of Waverly Place star Selena Gomez has all the confidence in the world, but the 18-year-old told TVGuide.com at Z100's Jingle Ball that her New Year's resolution is to stop questioning herself.

"I ask a thousand other people what I should do, so it's kind of nice to be able to trust myself a little bit more," she said.

One idea we hope she follows through on is getting on her dream show.

"I love the Big Bang Theory; I would love to be on that show," she said.
