Browsing last night, I found this passage, in a piece that may date from 1850. Good advice for anyone, lawyer or not, wanting to avoid procrastination and get things done:
Leave nothing for to-morrow, which can be done to-day. Never let your correspondence fall behind. Whatever piece of business you have in hand, before stopping, do all the labor pertaining to it which can then be done.Lincoln was born on February 12, 1809.
