Lowliness is young ambitions ladder, Whereto the climber upward turns his face: But when he once attains the utmost round, He then unto the ladder turns his back, Looks in the clouds, scorning the base degrees By which he did ascend. Shakespeare.Julius Cæsar, Act II. Scene 1. (Brutus to Lucius.)
Fool that I was! upon my eagles wings I bore this wren, till I was tird with soaring, And now he mounts above me. Dryden.All for Love, Act II. Scene 1.
