The person I use as proof that humanity is good is Dr. Seuss. He is an example of many things including determination, inspiration, and happiness. He used all of these aspects in his life and in his writing.
First, he is an example of determination because of what happened throughout his life. He struggled a lot when writing his books and getting them published. Theodore Seuss Geisel was a perfectionist so books could take him a year or two to write, but he never gave up on a book and that is why he has 46 children's books today. The first book he tried to get published (And to Think that I Saw It on Mulberry Street) was rejected 27 times before he signed a contract to publish it with Mike McClintock. This shows how Seuss would not give up on his book and on his career.
Secondly, Dr. Seuss is an example of great inspiration and creativity. He was one of the first to show that you are never to old to be a kid and he did this through his writing. Kids loved his books because it was something they could understand and connect to and believe in. Through his books Seuss was doing the opposite of killing creativity, he was nurturing it! There is a seed of creativity in every child's head and Dr. Seuss was helping it blossom.
Finally, Dr. Seuss is an example of happiness or joy. He had to go through some pretty hard things in his life, but he always remained happy. He took much joy in helping others with their problems and making kids happy with his stories such as Cat in the Hat and Horton Hears a Who. These stories were not only making kids happy, but they were teaching them a lesson. In every book Dr. Seuss has written, if you look real close, there is an underlying life lesson. For example in the Lorax he teaches kids how deforestation is evil and how we should preserve animals natural habitat.
All in all Dr. Seuss is a perfect example of the goodness in humanity. He is not the only one, but he certainly had a big impact on the world and will be remembered and cherished through his writing forever.
