This is, indeed, what life is in my experience: A series of "moments," all of which have their own worthiness... gratitude for "what is." It may not be what we thought it might be...
Much of it is a choice. Do we obsess over what isn't, or do we focus on what is?
Nature is all around us with its beauty; something that can always be appreciated... you have your river and the world around it; I have my bay and mountains; the world around them. And I'm grateful that I get to share those images with the world, here and elsewhere.
