While it is my understanding that expectations need to dropped to live in the HERE and NOW, it has also been my experience that the momentum of a life lived in constant expectation is impossible to bring to a stop through any act of will.
What has happened however, is that through maintaining a state of mind 'watchfulness', one has witnessed that the actual events occurring in my life have never exactly match my expectations. After many years, it is now my natural expectation that my expectations will never be congruent with reality as it happens. As a result, without effort, though there still may arise a preferred expectation as a result of my life's activity, the actual realized NOW result is more readily accepted without comparing it to any prior hope.
In other words, what happens is just 'what is', and in this state of acceptance, there appears nothing that needs to be changed as harmony is present with any and all changes taking place,....anything is possible!
