"To remind me that this is my life, and my story. When I look at this, I remember that I am strong, and that I, not those around me, am responsible for my own happiness. And by that same token, no one can bring me down. I’ve got this; I don’t need to be saved."
It stands for "Everything happens for a reason". Being able to recognize that everything that happens is part of the plan for your life, that you can't control it, and that everything will work out is one of the most important parts of living a happy life. And sometimes ya just need a little reminder. :)
