Colleen Patrick Goudreau is author, most recently, of The Joyful Vegan.

It's a book about joy, yes, but joy as a strategic imperative in a world that is relentless in trying to undermine our resolve about living compassionate and brave lives.

While steadfastness and willpower and outrage can provide bursts of energy for our journey, Goudreau asserts, it's joy that gives us the long-burning, clean fuel that allows us to come from love and compassion and understanding in all our interactions.
