Thanks for your comments. You're right, the term "giving back" is usually applied widely, in reference to a specific neighborhood or community of people or society at large. Most of the stories I collected for the book convey a sense of responsibility and mutuality that's prevalent among African American givers.
A definite takeaway message from Giving Back is that, whether you give your wealth, wisdom and/or work to dear causes, your intent and commitment are key to bringing about positive, meaningful change.
