Becoming an Actress

Ok. So I had an epiphany about becoming an actress a few years ago, and I decided to go for it. I moved from North Carolina to Atlanta thinking that I was going to be Tyler Perry's next big star. Hmm okay so I forgot that Atlanta is like... 90% African Americans. How in the hell was Tyler Perry going to discover me, or how was I going to get discovered. I looked for casting calls on Craigslist, southern casting call, and model mayhem just to find some type of work. I purchased expensive head shots trying to make sure that I had everything that I needed to impress the casting directors. 
  
 I had so many NO's and maybe a one or two call backs for extra roles, but I started to second guess myself. How can I stand out from everyone, and be different? What are the casting directors looking for? How can I audition for speaking roles instead of extra role? How can someone noticed me? Is this something that I really want?  

I want to show case my talent to the world, but I think maybe right now isn't my time yet, or maybe it's time that I put in more work into my craft.... I will keep you updated
