We learned in the past, but we are not a result of that. We suffered in the past, loved in the past, cried and laughed in the past, but that's of no use to the present. The present has its challenge, its good and bad sides. We can neither blame nor be grateful to the past for what is happening now. Each new experience of love has nothing whatsoever to do with past experiences. It's always new.
No way for most of this pufferific tripe. We are indeed forged and formed from all of our pasts, and all of the pasts of all of us. We stand, when we stand on the shoulders of many many fellows, including those of our own past, our own unique being growing, learning, making mistakes, falling getting up again. This quote is a bit dangerous -- in a bad way. It suggests, forget your spouse, your kids, run away with the dashing vagrant of a passsing fancy, because the past is nothing, and only this infatuation is NOW. Silly and utterly dangerous, harmful to many.
