More on the gratitude theme from Tom:

Very exciting to see the Amazon number drop, and I thank everyone for making it happen.

It takes an enormous amount of self-confidence to participate in a book tour--you just gotta believe.

When you guys show your support by buying books, it changes my entire outlook, bolstering my confidence dramatically.

And again, I can't thank you enough for it.

We appreciate you helping Tom to get the message out. Keep up the good work. And if you haven't bought all of the copies of GP that you're going to need yet...
