I am 14 years old (girl) and i would like to read any good self improvement books. I've read chicken soup before and to be honest, i don't really like it that much, So none of those kind of books. Also, this is a new genre of book that i am trying out so please tell me anything that will fit my age. I don't want to start out reading hard books because I probably won't be interested. Also, i'll be glad if it's enjoyable to read. Thank you!
