I agree Sarthak, that Douglass' endless determination was the cause of his success overall. I just couldnt help but ignore how he seemed to be in the right place at the right time. He even said, after being sent from his original home to a new home that his master could have picked anybody on that farm, but he was lucky enough to be chosen. Had he not changed homes, he may never have gotten the idea into his head that knowledge would be power. Had he not changed homes, he would never have gotten his foot in the door by learning to read a few words and letters. His determination was doubtlessly the reason he was so successful, he could have ignored all of this luck and ended up as any other slave, but his string of circumstances was very fortunate.
