what can we get from this?

I read this book a year ago.I remember I read it from the beginning to the end without having my supper. It was so fantastic that I thought it was not only a book about but about our human beings.About the essential aspects of people!! There are good thingsand bad things in our world ,and we will encounter a lot in our life .How can we try our best to handle it ?I think from the White Fang we can learn something that we must give our sincere effort to the things we should do and sometimes we need to abide something .Friends in our life are important,so from this story we know that just the sincere can get sincere.I hope every reader of this book can get something and find it useful in the future!!
