I have been called this. I have been called this many, many, many times throughout my life. Why, because I was always looking at all the ways anything could go wrong. I thought (I think I did anyway) that if I knew all the ways things could go wrong than maybe I could make the right decision.
The truth is that always focussing on all the ways that everything could go wrong, tends to stop you from enjoying the simple things in life.
Today – try to enjoy a moment. Not every moment, just one.
