I love all books by Dr. Seuss. Here are a few of my favorite quotes: 

“A book is just like life and anything can change”  From One Fish, Two Fish, Red Fish, Blue Fish

“So, open your mouth, lad! For every voice counts!”  From One Fish, Two Fish, Red Fish, Blue Fish

“ASAP. Whatever that means. It must mean, 'Act swiftly awesome pachyderm!”  From Horton Hears a Who!

“Don't give up! I believe in you all. A person's a person, no matter how small! And you very small persons will not have to die. If you make yourselves heard! So come on, now, and TRY!”  From Horton Hears a Who!

 “Today you are You, that is truer than true. There is no one alive who is Youer than You.”  From Happy Birthday to You!

“You have brains in your head. You have feet in your shoes. You can steer yourself any direction you choose. You're on your own. And you know what you know. And YOU are the one who'll decide where to go...”  From Oh, The Places You'll Go!

 “It's not about what it is, it's about what it can become.”  From The Lorax

“Then the Grinch thought of something he hadn't before! What if Christmas, he thought, doesn't come from a store. What if Christmas...perhaps...means a little bit more!” From How the Grinch Stole Christmas!

“Unless someone like you cares a whole awful lot, nothing is going to get better. It's not.” From The Lorax

“You’ll miss the best things if you keep your eyes shut.” I Can Read With My Eyes Shut!

“The more that you read, The more things you will know. The more that you learn, The more places you’ll go” From I Can Read With My Eyes Shut!

“I meant what I said and I said what I meant. An elephant's faithful one-hundred percent!”  From  Horton Hatches the Egg

“I know it is wet and the sun is not sunny, but we can have lots of good fun that is funny.” From  The Cat in the Hat

“Kid, you'll move mountains.”  From Oh, The Places You'll Go!

 “We throw in as many fresh words as we can get away with. Simple, short sentences don't always work. You have to do tricks with pacing, alternate long sentences with short, to keep it vital and alive. Virtually every page is a cliff-hanger—you've got to force them to turn it.”  Saturday Evening Post, October 23, 1965
