Fund consultant from Tanzania

"I never regret my decision to quit the medical profession because I'm achieving my success in a better way," said Patrick Samuel, a 42-year-old Tanzanian entrepreneur in Beijing.

When Samuel finished his medical education in Peking University in 2003, he landed a job as doctor with Peking University Third Hospital.

However, around 2007, China's rapid economic strides convinced him to branch out to the business of investments.
