I think this is coming from the Henry Ford quote, which is "Whether you think you can, or you think you can't--you're right."
This quote basically means that what you think you can do is all in your mind and how you perceive yourself. if you think you can do something, then you'll be able to do it. If you think you can't do something, then you won't be able to, because you have already given up in your mind.
Does that make sense?
In order of this:
Climax
Falling Action
Exposition
Resolution
Rising Action
I would think anyone would feel stronger having a rifle on them. But do you have a passage for this or something to be sure?
He tells about his story as a child growing up to where he was when he made the book. His story showed the unfairness in being a slave.
The source could be wrong or biased or both.
