Gladwell's book provides some really useful principles for social innovation, along with really interesting examples. It highlights some simple but often overlooked factors in our behaviour and social interactions.

The theme of the book is simple, how little things can make a big difference. We recommend this book to our student, and tell them that they do not have to be a superhero or rocket scientist to create a better world, there are a lot of little things that designers can do to make improve people's everyday life.
