hello all

A while ago I found an excerpt from Schopenhauer on a blog. It was translated to dutch and there was no note about the source, just the author. I suppose the original is in german, and I'd like to know which book/chapter this is taken from? Anyone seen this before? Maybe it was something he just wrote or said somewhere and its not in one of his books, but would like to know that.

here it is, I translated it to english:
"When you are at the end of life and look back at it, at the course of life and the encounters and events, which at the moment itself seem to be coincidences, but in hindsight appear to be crucial for the structure and character of an unintentional life story, by means of which the potential possibilities of somebody's character come to surface, if this is seen, then it is hard to resist the idea that the course of somebody's biography can be compared to a sneakily orchestrated novel, while you wonder who could be the writer of such an amazing plot. The whole linkage of world history actually exists of life's destinies that unfold in time as an immeasurably large network of this kind of influences, that not just limit themselves to people, but also the natural world with all its creatures and all kinds of accidents."
- Arthur Schopenhauer
