When Tyrone, 41, can't make his Alcoholics Anonymous meetings, he relies on something else to help him stay sober: text messages. The daily recovery-themed messages from a company called I Live Inspired remind him to "look to my higher power for guidance, and accept life," he says, quoting a recent dispatch. I Live Inspired is the brainchild of Rob Foster, a 28-year-old former cocaine addict from Virginia who came up with the idea after his second rehab stint in 2006. A friend sent him texts about sobriety every morning as Foster traveled to work "feeling crazy." The messages made him feel less alone, so he started forwarding them to others on the mend. Soon a business was born: $3.95 a month for daily bytes of inspiration sent to any cell phone.
