Be careful who your driver is when you jump into a cab these days - they just might be a financial genius.
I came across one just yesterday. Like many people, he regularly sends money to his siblings and extended family back home. However, after seeing it being spent on "perishables" for years, he decided on a new rule of thumb: he wasn't going to give money for family to spend on food anymore.
(He reassured me that no one was in real danger of starving.)
What he would give generously for, he explained, was anything to do with starting a business.
