I bought a book a while ago that I was really interested in, but when I sat down to read it, just wasn't feeling it. Instead of getting frustrated, I listened to the feeling, put the book back on my bookshelf and said to myself I'll pick it up when the time is right.
Cut to a few months later and I'm writing a script about dreams. I look at my bookshelf, wanting to read something knew, but not knowing what. And there it is, crammed way in there: the book. I pick it up. Lo and behold, the first story is a story all about dreams - a story that inspires and fuels me in my own writing.
Basically, what this taught me is to trust the process. Being open means that it will all happen when it's supposed to. You've just gotta let it in.
