The expectations of life depend upon diligence; the mechanic that would perfect his work must first sharpen his tools.
Few things are impossible to diligence and skill.
The History of Rasselas, Prince of Abissinia (1759)
The leading rule for the lawyer, as for the man of every other calling, is diligence. Leave nothing for to-morrow which can be done to-day.
The fine points that are uncovered in our work as a result of close study, diligent care, constant application and always trying to improve our methods represent the best and most valuable knowledge we get in business-and the sum total of that attentive attitude is what we call skill.
Seest thou a man diligent in his business? He shall stand before kings; he shall not stand before mean men.
Bible, Proverbs 22:29
