There is an old saying "well begun is half done"-'tis a bad one. I would use instead-Not begun at all 'til half done.
John KeatsThis living hand, now warm and capable Of earnest grasping, would, if it were cold And in the icy silence of the tomb, So haunt thy days and chill thy dreaming nights That thou would wish thine own heart dry of blood, So in my veins red life might stream again, And thou be conscience-calm'd. See, here it is-- I hold it towards you.
John KeatsO Solitude! If I must with thee dwell, Let it not be among the jumbled heap of murky buildings
John Keats
