"The sun is always shining someplace."- Muhammad Ali. "In life, in true life, there can be nothing better than what is." - Leo Tolstoy. "I've got nothing to do today but smile." - Paul Simon. "Nobody can be uncheered with a balloon." - A.A. Milne. 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 a glass-half-full outlook. Building on Kathryn & Ross Petras'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-good times--(recovering from an illness, coping with a loss, or bouncing back from a difficult time). Here are quotations that tap into a wellspring of joy, inspirational ideas on gratitude, hope, love. and laughter.
