The King of the Land of Regret

I am the king of the land of regret.
I am the seer of all that might have been.
I am the empty promise, the bad debt.
I am the gambler that can never win.

I am the sad ghost of my ambition.
I am the shadow of what I should be.
I am the unrepentant contrition.
I am the painting you will never see.

I am the shriveled seed stored on a shelf.
I am the dream forgotten when waking.
I am the ego in search of a self.
I am the plan always in the making.

I am the telephone that never rings.
I am the letter that was never sent.
I am the song bird that no longer sings.
I am the rose without a pleasant scent.

I am the sum of all I was before.
Given that, shouldn't I be so much more?
