I Am Jealous Of My Younger Sister.

Since I was about five or six years old, I have dreamed about being involved in the entertaiment industry- being an extra, acting, working behind the scenes, anything. I have started really going for this goal in the last two years but have had no luck. My sister, who is three years younger than me and tries to upstage me in everything I do, started trying to become involved as well in the last month. A few days ago, she got her first job after trying for only a month, while I have been at it for two years. I am happy for her, of course, but I can't help but feel that it should have been me that got the job. I'm afraid that she's going to use it against me and tease me that she got a job before me when she was only 13. I'm trying to get rid of the jealousy and be comfident that my turn will come eventually, but it's hard.
