I remember when I was writing my first screenplay! I just knew it would sell right off the bat and, besides that, not only was it going to sell but several major studios were going to be pounding down my door for my next one.
Now, five SP’s later, I realize just how wrong I was and how much more I have to learn. It’s a process. I finally understand that. Realizing that seems to take a lot of the pressure off… At least for me.
If you are just starting off, give yourself time to hone your craft. Realize you are going to make mistakes. And when you make them, learn from them. Realize success won’t happen overnight.
Then, one day, maybe a studio or two will be pounding on your door! (And mine, too!)
