We can be encouraged by what we see or frustrated by what still seems to hold us back, but we can't do both at once.
When people come to the fence to talk to my dogs, I have noticed that, as much as the dogs would like to be on the other side of the fence, they waste no energy in regret or resentment. It is all about wagging tails. They are happy with what the open space provides. They can make enough contact, and see enough, and smell enough that they are content with the moment's offerings. They know that other moments offer other things, but they don't have to have it all at once.
I think they are offering us a good model. Choose not to be frustrated with the 'old' but rather to relish what we get when we get it of the 'new.' Dogs are always just being themselves so, we can likewise just fill the moments of the 'not quite fully here yet' of the New World with just the "is-ness" of being ourselves. It is enough. We are enough. If only we would get that.
