A 72-year-old Uber driver who earned $80,000 last year explains how he avoids burnout and why it's become harder to make money on the app

• Rich, 72, earned $80,000 last year driving for Uber.
• He said more drivers and fewer app promotions mean it's more difficult than ever to make money. 
• Engaging with customers helps him avoid burnout during long shifts.

Rich, a full-time Uber driver for more three years, said it's not uncommon for him to start working as early as 4:30 a.m.

"After I have my coffee and watch a little news I start driving," he told Insider.
