I told myself, "Lincoln, you can never make a lawyer if you do not understand what demonstrate means." So I left my situation in Springfield, went home to my father's house, and stayed there till I could give any proposition in the six books of Euclid at sight. I then found out what "demonstrate" means, and went back to my law studies.
The first in time and the first in importance of the influences upon the mind is that of nature. Every day, the sun; and after sunset, night and her stars. Ever the winds blow; ever the grass grows.

The art of wealth-getting which consists in household management, on the one hand, has a limit; the unlimited acquisition of wealth is not its business.
