I had to reply to this - I am SO feeling this too! Like you, I am not expecting anything to happen per se on the day, in fact I think it's already happening and will continue after.
I feel like the whole world has just sort of clicked into a place and we are gliding...yes gliding. No need to really struggle or ponder, or try to figure anything out...because we are all headed in the same direction. Such a smooth feeling.
Ordinary day to day things are becoming less important and distracting for me. I feel lighter. It's great!
