My classroom: the City - its parks and natural areas, commercial corridors, transit lines, diverse neighborhoods, public schools, array of creative local entrepreneurs, vacant land and brownfields, creeks and rivers and wetlands, and its beating heart. My fascination: the untethered mind of an entrepreneur. My teaching fuels: curiosity and wonder. My teaching application: the practice of the Ps of eco-social entrepreneurship: Planet - People - Profit - Passion - Pissed-off-ness - Partnership.
