—Karl Marx (1818–1883)
“...there is a difference between being convinced and being stubborn. I’m not certain what the difference is, but I do know that if you butt your head against a stone wall long enough, at some point you realize the wall is stone and that your head is flesh and blood.”
—Maya Angelou (b. 1928)
