A big reason is that not enough people are trying. When I say trying, it takes huge determination because it is a very risky career. Most Asian families do not encourage it and that is probably one of the biggest reasons. People shouldn't hire you because you are Asian or because there isn't enough diversity. People should hire you because you are extremely talented and you try really hard .
Diversity is never the key.
What is going to sell you is that you have something special. I have a few things that I'm preparing, but I don't know which one will get off the ground first. They are directing projects, because acting projects I cannot prepare. I go out on auditions and either they want me or they don't want me. For directing projects I can continue to read, continue to polish the script, raise the funds.
