Just know that being and actor in general is a hard and frustrating career. People in the business say that an actors job is to audition, which honestly it is. My advice is , one to really dig deep and ask are yourself are you ready to whats to come cause the results may not be pretty. if you will do whatever it takes and acting is your burning passion i suggest you take a few professional acting classes. I go to a performing art school and before coming i thought i knew it all and in all honesty no one truly ever does. acting is a sport so you have to practice. That's one! to build your career since you live in such a small area with little exposure to theatre or film in general you could join a local trusted agency or move to a city near you with great acting opportunities. if you have the money i suggest Houston or Dallas. Living in Houston for so long i didn't realize how big of a theatre community we had so making connections is a great way to build your acting career. Obviously moving is extreme but location and where you are is important especially if you want to be a film actor (thats why you hear so many people move to LA or New York), but if you are staying in Arlington i would do some research of some short film makers in the area contact them because it may seem like a little project but many short films grow popular on youtube, tumblr, etc. which is how many people are getting recognized. Don't be afraid to reach out to local artists and maybe research of there is a music video that needs to be shot. whatever your goal is you have to work for it especially in this profession but you got to make it work for your situation. I hope i was of help to you, if you have any questions keep me posted!
