Beautiful pictures are developed from negatives in a dark room... Always remember this when things are going wrong or you don't see a "positive" in the situation your in.
So if you see darkness in your life, be reassured that a beautiful picture is being prepared... So when you are in that situation, always, always look for the positive in the situation. What can be learned? What can and will be done differently? How will you approach it next time? Use the negatives now to make the positive of the outcome (The Picture).
