What can we learn about marketing from this Uber driver who earns 252K a year

In my previous life my mentor Bertus Gardien taught me always to look out for an sales opportunity. I was reminded of this when I read the Forbes story about Uber driver Gavin Escolar. It´s not with his taxi that Gavin earns his money. He uses his car as a showroom for his jewellery business. Driving for Uber he met about 3820 prospects over the past 18 months and as such earned an income of 252,000US$. Gavin talks to all his passengers about his hobby business and it has results.
I´m not sure if all of our readers feel comfortable talking about their business to everyone they meet, but thinking about where and when you can find clients is something we can learn from Gavin. You carry your showroom with you always on your smart phone. Read the full story by Forbes journalist Jon Youshaei via this link.
