Query: a good kids self-esteem book

I really liked this book, "Don't Feed the Monster on Tuesdays!" Before I read this book I used to think negative thoughts about myself every day. This book helped me realize that other people, even adults, experience the same thing that I did. I took your advice and reminded myself to think only nice things about myself. I even made a sign to hang in my room. I'm happy to say that your book really helped me. Keep up the good work! Thanks!
