I had to read the book twice, once in 8th grade and once in 10th. The first time I read it, I remember thinking after the first chapter about how much I would detest Gandalf if I were Bilbo. If you were sitting around in your own home, minding your own business, you probably wouldn't like it much either if some dude you'd never met came barging into your house and invited 13 more people you didn't know to come in and eat all your food.
Though in defense of the dwarves, they did wash the dishes afterwards. (source)
Needless to say, Bilbo wasn't too happy either, and initially wanted nothing to do with Gandalf or the dwarves. But he eventually came around.
If you're not familiar with the story, here's what you need to know: Bilbo, who was also in Lord of the Rings, is the central character in this story, which takes place 60 years earlier. Gandalf wants Bilbo to accompany 13 dwarves on a quest to reclaim their homeland, which was taken from them by the dragon Smaug years earlier. Smaug now lives in the Lonely Mountain and guards the treasure that was rightfully the dwarves'. Gandalf chooses Bilbo as the 14th member of the company because he is stealthy and light on his feet, and because he is a hobbit, and a dragon might not recognize a hobbit as easily as a dwarf.
As one point in the movie, Thorin (the dwarf prince leading the quest) expresses his doubt of Bilbo. Bilbo, like most hobbits, gets homesick easily, and desperately misses his warm bed, food, and his garden. But Bilbo insists that he's not going anywhere. Sure, he misses his home -- but he's not going back. Why? Because he has a home. The dwarves don't have a home to go back to, and he is going to help them get theirs back.
Awwww...so touching! (source)
Other than the heartfelt humanitarian message, The Hobbit has an important message about living your life. Bilbo could have sat in the comfort of his own home and been rather happy, but instead chose to do something hobbits rarely do and ventured outside his comfort zone. And if he had never gone on this unexpected adventure, he never would have told such amazing stories to Frodo and other hobbit children. And if Frodo had never heard these stories, he might not have been as willing to go on a quest of his own. And Frodo's quest went far beyond helping strangers -- the fate of his entire world rested on his success.
People who are successful have made it happen on their own; very rarely do they just fall into it without any action. But getting yourself out there and taking action can help more than just you. It can benefit everyone.
