Some days for Rachel Jordan start at 5 a.m. and don't end until midnight — sometimes for multiple days in a row.

The Florida resident, 43, is one of the millions of Americans who work two jobs to get by as they try to pay down debts they incurred early in life. With about $75,000 in outstanding student loan debt, Jordan often works 70 hours a week to pay it down but worries she's still financially behind.
