Believe it or not, it's possible to make a positive difference on the world. While some are happy to spend their time proclaiming moral superiority or expressing outrage over another person's behavior, others would rather use that time to make the world a better place. This commentary provides some common sense options that are easy to understand, but often challenging to implement. If you want to improve the state of the world, this is a great place to start. While often addressing life on the Internet and interactions common on social media, 13 Things presents information that applies to all types of interactions with other people. Complete agreement isn't always possible or even necessary, but there are ways that we can behave to make differences of opinion more palatable. 13 Things encourages everyone to live in a way that really does make the world a better place by suggesting things like patience, tolerance, fewer self-inflicted wounds, actual interest in others, and a number of other behaviors that are honest and positive. Readers are also invited to participate in creating the next version of this book through providing ideas for new content. This unique approach to iterative development may be of interest to others who are truly committed to making the world a better place and do not want to take on the responsibilities of writing an entire work by themselves.
