Missing the past

Life changes bring about new opportunities. New chances. New possibilities.
The also, inevitably, leave something behind. Perhaps, that one thing that got left behind was that which actually made the change possible. Perhaps it is a small piece of the puzzle. Perhaps it was bigger.
But it got left behind. For whatever reason. That doesn't make the change less wonderful. It doesn't make the new opportunity any less important.
Happiness about the new doesn't mean sadness about the old is automatically out of the question. No, indeed, sometimes missing the past makes the present that much more cherishable.
