Things may come to those who wait,
but only things left by those who hustle.
I wonder if the word "hustle", to aggressively pursue -- customers, wealth, whatever-- was used in that sense in Lincoln's era.
Other, older meanings of "hustle" are to hurry about (in a scattered way); to prostitute or to con.
The base quote from which this seems to be derived is Longfellow's "All things come round to him who will but wait" (Bartlett's Quotations: "Tales of a Wayside Inn.") http://www.bartleby.com/100/437.52.html
Bartlett's online does not give up a Lincoln quote. Yet if you do a google search on this quote you will find it all over, and attributd to Lincoln.
I hope someone can help me out with this one
