“One of your greatest faults as a scholar is the want of perseverance, to struggle with little recurring difficulties; you too readily give up, before making suitable effort to overcome them. This propensity you must correct, or you can never attain to anything great or excellent. Remember what Virgil says:– ‘possunt quia posse videntur’, a motto which you will recollect I told you should be inscribed on everything you undertake.”

Daniel Adams, M.D. to his son Daniel Lucius Adams
