Query: Excellent! Buy 25 for your friends!

Short, powerful and life-changing. If you already have a generous spirit, you'll be inspired and motivated to be more generous. If you have friends or colleagues,who, with encouragement, could begin to experience the joy of generosity--they'll never forget your help in pointing them in the right direction. I hope this is Ken Blanchard's all-time best-selling book!
