There really always is something to celebrate, as Kathryn Petras truly learned when undergoing treatment for breast cancer. And that was the genesis of "Nothing is Worth More Than This Day" - a book with glass half full outlook. Building on Kathryn & Ross Petra's successful series of quotation books, it's the perfect gift for the good times (birthday, graduation, Mother's Day, a new job) and even the not so goo times. Here are quotations that tap into a wellspring of joy, inspirational ideas of gratitude, hope, love and laughter. "Nothing Is Worth More Than This Day" shares the words and thoughts from a wide range of people including George Carlin, Judy Blume, Frida Kahlo, Marcus Aurelius, Louis Armstrong, Charles Bukowski, Michael J. Fox, Maya Angelou, Jack Kerouac, Buckminster Fuller, Andy Warhol, Anne Frank, Johnny Depp, Anthony Bourdain, Goethe (the source of the title quote) and many, many more.
