Identifying a Problem

I've learned that one of my main problems is that I'm too focused on being correct. I'm not letting things happen spontaneously in a scene. I'm searching for a particular way for something to be done and that simply doesn't exist. Every scene is done differently. Everyday you will bring something different to the scene. A different director may have a different view from another director. There are so many variables that there can't be one set way to do something. Part of me has always wanted to make sure I'm doing whatever I'm doing correctly and since there is no correct way of doing a scene, it's making this film/drama type of acting very difficult for me. I've made progress but there is a lot more to be done. What I have to do exactly, I'm not exactly sure as I'm still trying to process everything. I'm moving one step at a time and trying to look ahead and plan everything out like I usually do.
