You will win or you won’t.
You will achieve all your goals or you won’t.
You will be happy and healthy for all your life or you won’t.
There is always a possibility that things will go south, that shit will happen and you won’t have what you want. It’s the other side of spectrum, whatever there is a chance for something good to happen, there is also a chance for it not to happen. No matter the game, there is a chance that you will lose it. It doesn’t matter whether you know and think about it, it may happen.
