Deficient Sufficiency

Met have I An Incorrigible, Who thinks himself The Eligible For manning of a dirigible: For all valued posts The Preferable And The Toughest of The Capable... To his admirers infallible But to cheap impulse susceptible And to pettiness vulnerable... Yet, has he been quite acceptable, His best doing to be fashionable Always after the presentable His self - image not winnable. Still, it's been a voice inaudible Speeches soon unintelligible From ideas incomprehensible Only a bit understandable; In many ways, then, The Sufficient And in as many The Deficient.
