Power is poison. Its effect on Presidents has been always tragic, chiefly as an almost indecent excitement at first, and a worse reaction afterwards; but also because no mind is so well balanced as to bear the strain of seizing unlimited force without habit or knowledge of it; and finding it disputed with him by hungry packs of wolves and hounds whose lives depend on snatching the carion.
Henry AdamsIf any one of us has had an ambition higher than that of making money; a motive better than that of expediency; a faith warmer than that of reasoning; a love purer than that of the self; he has been slow to express it; still slower to urge it.
Henry Adams
