As a writer I wonder how those wonderful classic inspiring words happen to fall in with all the who, where, why, and whats. Definitely, it's a moment of inspiration that was put onto the paper (classical quotes usually were on paper, not digital). I wonder how many times the author moved the words around, trying to show this nugget to its best advantage. Maybe they thought great things like that all day long. Maybe. I tend to think of it as hard work and an understanding of human nature.
Read the quotes, then tell me what you think.
