Things will not always go how we hoped they would or planned for them to go.
In fact, maybe most of the time things will go differently than we wished or assumed they would.
This is simply part of the path.
We cannot control every detail, variable, and circumstance so that all of life conforms to our will, our plans, and our designs.
That is an impossible task and one that will leave us exhausted, frustrated, and disappointed if we attempt it.
Instead of even trying, we are much better off accepting how little we truly know, preparing to be adaptable to the inevitable changes that will come at us, and embracing the mystery of the moments that lie ahead of us.
Life is much more interesting and enjoyable when we let it happen and participate in the happening than when we limit our experiences to our finite imaginations and desires anyway.
