Mindfulness is a popular mantra these days. There are dozens of books on how to practice it in all aspects of life, from eating to relationships to education. For Gretchen Steidle, practicing mindfulness changed her approach to her work in the nonprofit sector. She has written a book called Leading From Within: Conscious Social Change and Mindfulness for Social Innovation, which looks at how organizations and companies can benefit when leaders invest in mindfulness and bring it to the workforce. Steidle, who runs Global Grassroots, spoke to Knowledge@Wharton about the transformational process of mindfulness. Following is an edited transcript of the conversation.
