He lists both seven gifts and seven givers who can impact the lives of those they interact with. The seven gifts are encouragement, energy, enthusiasm, empathy, good humor, graciousness and gratitude. Each gift is explained in its own chapter with plenty of examples that Hewitt has witnessed in his own life. The seven givers are the spouse, the parent, family members, friends, the coworker, teachers and the church.
I wish this book could have been more focused on the message, instead of using every opportunity to bash those with differing political or ideological viewpoints from the author. There are many snide comments and belittling asides about those he perceives as not having he same viewpoint he does. There's also so much name-dropping and thanking of those who have helped the author along the way that the book becomes very tedious in places. I think if you can look at his seven gifts, and realize that they can be "given" freely and without much effort to friends and strangers alike, you don't really need to wade through the self-congratulation that makes up the bulk of the book.
