When we think of retirement, it may be that visiting exotic islands, lying in hammocks, and enjoying endless days of leisure come to mind. Well, that’s not Estella Pyfrom’s idea of retirement. Pyfrom, a retired teacher and daughter of migrant farm workers, spent all of her retirement funds ($900,000) to serve others. She bought a bus, decked it out with computers and desks, and now drives throughout the district where she taught, providing a place for underprivileged children to do homework and learn technology. Struggling students flock to what she’s labeled the “Brilliant Bus”—and find hope.
