An Emptiness In My Sawdust

Sometimes I feel a hollowness in my self. It's like being a doll that does not have enough stuffing. Why would someone feel incomplete when there is nothing to complete? After all, if one knows one's limitations and what one never had, one should cease to desire it. It's impossible to obtain. Still, one cannot help but know there will be something out there to fill the emptiness to overflowing.
