“Be sure you're right-then go ahead.”
“Remember these words when I am dead. First be sure you're right, then go ahead.”
“Know your right, then go ahead.”
“You may all go to hell and I will go to Texas.”
“Fame is like a shaved pig with a greased tail, and it is only after it has slipped through the hands of some thousands, that some fellow, by mere chance, holds on to it!”
“be always sure you're right, THEN GO AHEAD!”
