oneword: wanting

why does it always seem as though what you want it always waiting for you on the other side of the fence? is the grass always greener over there? i don't want to spend my life jumping fences to see if it really is. i want to be able to look down at the grass on my side of the fence and breathe out a sigh of relief and be thankful that I am on my side of the fence, even if there is a little brown patch.
