Be an extra as much as possible. Local film commissions are good to call. Do a a lot of community theater too. Take an acting class and start building a resume. Then start submitting to agencies. My advice is to stay at least a few months where you're at with an agent and go for the bigger auditions before you move to California. California is not as "unreachable" as dream crushers say. Get room mates and most importantly save up now. There are a TON of short films and indies in Cali that you can load up on your resume, and a ton of opportunites to be an extra. Do that first, get as much experience as you can, and try to get an agent. Also, if you can think of anything else in life that you'd be just as happy doing, then do that, and trust me you're life will be happier. If you can't...then do this. Thats a quote of wisdom I heard and it stuck with me. But most importantly, shut your ears and block out negativity. And start doing that RIGHT now cuz its about to crash on top of you if you want to do this for your life.
