Positive Visualization . Trust me, you're going to go through some dark times. You absolutely must remain focused on the positive future. Visualize where you see yourself at every next step along the way. Soon you look back and realize you've actually gone somewhere.
Visualization is key.
As far as your scripts go, keep writing. Keep sending them to whoever will read them. Just know that you can't expect anyone to do it for you. You have to do it yourself. And if you really need to, you'll shoot your movie on 8mm.
