''I have filed away at least a million things to thank you for, but somehow I never got around to actually telling you what I felt nearly as often as I wanted to.'' -BTG, inside THANK YOU FOR BEING YOU New York Times best-selling author Bradley Trevor Greive (BTG) knows a thing or two about offering thanks. He has penned 15 book titles that have been published in more than 105 countries and have sold more than 15 million copies. That's an awful lot of thank you letters to write, so BTG decided to pen the ultimate acknowledgement of appreciation ideal for expressing a range of gratitude-induced sentiment. So, for all the thank you letters you may have sent, and especially for those you forgot to mail, consider this the long-overdue, but perfect message.
