Actor. You get a chance to explore more sides of yourself, you have more time to prepare for you projects and you promote things on a quieter level than singers. I feel like the music industry is rushed and that the singers are controlled by the label. Plus, when you're an actor, you can play a singer. When singers act, it doesn't usually go well.
I've always loved singing. I even joined my school's Choir my Junior Year and eventually one the award for Most Improved Singer (which I consider to be my school's version of a Grammy) at the 2011 End of the Year Choir Banquet which was voted on by all of the people in all of the choirs in the school (I was in Mixed, so I was voted on by people in Mixed, Women's, Jazz, 2 and 4, and Concert Choir).
I'd love to act too though. Comedy especially. I just need to work at it. I would absolutely LOVE to play a bitch! Or a ****! Or an idiot!
