Student who doubled as high school's custodian now Harvard-bound

Homeless to Harvard:At 6 this morning, long before her classmates were even awake, 18-year-old Dawn Loggins was already pushing a mop through her high school in Lawndale, N.C. -- where she also works as a custodian. "I think that what got me into Harvard was my drive," Dawn said. "And the fact that I've been able to do so much, with everything working against me. Imagine what I'll be able to do when things are actually going like they should."
