365 Thank Yous: The Year a Simple Act of Daily Gratitude Changed My Life by John Kralik
I'm glad my mom trained me to write thank you notes. A gift shows that someone thought of me and took the time and energy to give me something they thought I would like. It's only polite to thank them. Plus, it's good for my own heart to remember that everything is a gift and I'm really not entitled to anything.
In response to unfortunate events and circumstances, John Kralik vows to write a thank you note a day. The effect that this has on his own emotional well-being, his relationships, and his business is inspiring and encouraging. You might just want to write a thank you note after you read this book. :)
