Here is an assignment for you to demonstrate in a personal way how unexpected events are strongly connected to your possible futures.
Pick something important in your life – it can be anything. Now trace backwards in time to events that lead to the fact of this important thing in your life. For each event, make a mental note of whether the event was expected or unexpected. Continue this until you find a totally unexpected event. You will find one – there is always at least one and often more than one. Analyze the connectedness of these events and look for those unexpected events that you could have used to see into your future.
