We all like to tell stories; the stories of our lives... It's how we relate to one another, bond and make forever friends, isn't it?
We embellish them here, flower them up there, tell the truth-as-it-is for the sake of accurate and actual accounts. We provide the sequence of unfolding events along the way, dragging up all the good, the bad and the ugly parts that got us to where we are and made us the person that we are now.
While it may make for a good story, what you think and talk about and how you feel about it - becomes.
You're always creating your now (because it's now and you're having the experience of it now as you're telling it) and you're also pre-paving a future reality.
