There is this movie called Mr. Nobody. It's a good sci-fi movie you should watch. But I will just go straight to the point. The movie teaches us that even if we had the ability to change parts of our story, no matter the outcome, they are the right story. I think that one way to cheer yourself up, is that everything is the right choice. It is your story. No matter what the ending is, is the correct story. So when I am met with this, I don't think about what if I did this another way, or this way. I just tell myself what I am going to do, is leading me to the right place.
