Why did Tina write the book?

I think the author, Tina Fey, wrote the book Bossypants not just as a memoir but she wrote it to make people laugh every page they read. Tina is a comedian so obviously her book is going to be hilarious (at least I had hoped when I picked the book) and It is. In the beginning she talked a lot about her awkward teenage years (which I can completely relate to because I'm going through them right now). She wrote the book in a way people of pretty much all ages can relate to and I thought that was really neat because I can relate to some of the stuff now and I'll probably still be able to relate to it as I get older. Of course you want people to be able to relate to you because that just makes it all the more interesting to read. Also she probably wanted to get her story out there, so people who loved her movies could get to know her on a more personal level, because having a book about someone's life makes it way easier to get to know them, rather than watching hours of interviews. In part of her book she has fan/ hate mail that she answers (sarcastically) and it really shows you that she doesn't really care anymore and that writing horrible stuff about her on the internet (Perez Hilton) doesn't affect her, which is good because way too many people care way too much about what people say about them. This book is really just a confidence booster for women because it shows that even celebrities aren't perfect, that when the award show is over they just go home, put on pajamas and shove their face with potato chips.
