Bad company is like a nail driven into a post, which, after the first and second blow, may be drawn out with little difficulty; but being once driven up to the head, the pincers cannot take hold to draw it out, but which can only be done by the destruction of the wood.
Saint AugustineDo you wish to rise? Begin by descending. You plan a tower that will pierce the clouds? Lay first the foundation of humility.
Saint Augustine
