Change lifestyle. Stop spending more than he's earning (delay gratification), He obviously has loans so pay off the highest interest loan first followed by the rest, cut up credit cards, reduce nights out with friends to once a month (if he must drink buy take away from a smarket it's much cheaper), Hook up to DStv (stay home more), start investing/buying assets, sell the car, dump high maintenance, go back to school, read novels.... I can go on and on and...
BBI will solve it :)
