What happened before is only a guide to the future if we choose it to be.
This unfolding now moment is unique as each next moment will be, nothing is determined by before except for our own minds and the repeating story.
The past does not exist, it is just a mental concept, a memory in our head or in the collective mind.
If we enjoy this moment now, and if we accept what is and allow this moment to unfold without our mental constructs or judgements based on the past, then who knows what can happen!
We create our reality, why choose to repeat the past?
