A fascinating look in the video above at the earliest writing we have from Abraham Lincoln, his “sum book”. The tenacity with which Lincoln pursued education and self-improvement as a child and young adult is awe inspiring, especially in our age of free public education for all, and the knowledge that many students fail to make much use of this opportunity. Lincoln’s thirst for knowledge remained with him all his life. In his eulogy for Henry Clay in 1852 he stated, Mr. Clay’s lack of a more perfect early education, however it may be regretted generally, teaches at least one profitable lesson; it teaches that in this country, one can scarcely be so poor, but that, if he will, he can acquire sufficient education to get through the world respectably. I suspect that Lincoln thought that quote applied to him, just as much as it did to Henry Clay.
