How does the book Dr. Jekyll and Mr. Hyde relate to one of these three quotes?

i have to write a paper on how the book Dr. Jekyll and Mr. Hyde relates to one of these quotes. it can be as easy as how Dr. Jekyll (or any other character in the book) relates to one of these quotes please give as many examples as you can thanks!
1. "courage is the ladder on which all other virtues mount"
2. "experience teaches slowly and at the cost of mistakes"
3. "the aim of life is self development. To realize ones own nature perfectly- that is what each of us is here for"

THANKS SOOO MUCH!
