Having an objective/obstacle

In every show, with every character there is always an objective for everyone, but at the same time there is always an obstacle they have to either overcome, or subdue to. An objective is what your character wants. If i was a coffee addict in my scene, my objective would be to go get some coffee. An easy obstacle in that scene could be that there is no milk left. Now most people would think, well than you won't have coffee today, but that contradicts my character. So there are a couple options to think about. I could go buy some milk or i could drink it black (which means without milk). These are ways to get around an obstacle. There is always multiple options, just think of them all. Objectives and obstacles, just like secrets, can affect the way you move around on stage.
