It seems difficult, but if you can let just let all of your expectations go and simply be in the moment, the experience of living takes on a whole new meaning.
Of course the hard part of achieving this state is actually letting go of what you want to happen, of what you think should happen. Stop trying to control things and just let the experience of living wash over you. It makes being in the world a place of endless possibilities, like you are experiencing life as if you were a child.
When you are feeling overwhelmed, putting yourself in this zen-like state can open up fresh perspectives, allowing you to see new possibilities.
