The wind never blows the same way twice.
Sit beneath a tree, you will note the rippling, swirling and swooshing wrapping around each branch and through each finger of leaves will never be quite the same each time.
People change. The forces acting around us and through us are working a divine kind of magic.
Don't ever fix a view of the scene, the person opposite you or even of yourself. We are constantly ebbing and flowing and consistently changing.
The moment you are certain about the past or the future - reassess, reposition and think again. The only certainty we have is in this very moment - everything else a facade.
