Simple Matters is Erin's 2016 book. It's a nod to the growing consensus that living simply and purposefully is more sustainable not only for the environment, but for our own happiness and well-being, too. Filled with personal essays, projects, and helpful advice on how to be inventive and resourceful in a tight space, Simple Matters shows that living simply is about making do with less and ending up with more: more free time, more time with loved ones, more savings, and more things of beauty.
